Ancestry and pathology in Tutankhamun's family

My inbox and my news alerts have all gone mad with the news about the Tutankhamun DNA results released by the Supreme Council of Antitquities. Thanks so much to everyone who sent links! Much appreciated, particularly given that I am away from home at the moment.

I have tried to avoid excessive duplication but here are the main themes from all the pieces that I have read so far. See the links below for the full stories.

Context The New Kingdom in ancient Egypt, comprising the 18th, 19th, and 20th dynasties, spanned the mid-16th to the early 11th centuries BC. The late 18th dynasty, which included the reigns of pharaohs Akhenaten and Tutankhamun, was an extraordinary time. The identification of a number of royal mummies from this era, the exact relationships between some members of the royal family, and possible illnesses and causes of death have been matters of debate.

Objectives To introduce a new approach to molecular and medical Egyptology, to determine familial relationships among 11 royal mummies of the New Kingdom, and to search for pathological features attributable to possible murder, consanguinity, inherited disorders, and infectious diseases.

Design From September 2007 to October 2009, royal mummies underwent detailed anthropological, radiological, and genetic studies as part of the King Tutankhamun Family Project. Mummies distinct from Tutankhamun's immediate lineage served as the genetic and morphological reference. To authenticate DNA results, analytical steps were repeated and independently replicated in a second ancient DNA laboratory staffed by a separate group of personnel. Eleven royal mummies dating from circa 1410-1324 BC and suspected of being kindred of Tutankhamun and 5 royal mummies dating to an earlier period, circa 1550-1479 BC, were examined.

Main Outcome Measures Microsatellite-based haplotypes in the mummies, generational segregation of alleles within possible pedigree variants, and correlation of identified diseases with individual age, archeological evidence, and the written historical record.

Results Genetic fingerprinting allowed the construction of a 5-generation pedigree of Tutankhamun's immediate lineage. The KV55 mummy and KV35YL were identified as the parents of Tutankhamun. No signs of gynecomastia and craniosynostoses (eg, Antley-Bixler syndrome) or Marfan syndrome were found, but an accumulation of malformations in Tutankhamun's family was evident. Several pathologies including Köhler disease II were diagnosed in Tutankhamun; none alone would have caused death. Genetic testing for STEVOR, AMA1, or MSP1 genes specific for Plasmodium falciparum revealed indications of malaria tropica in 4 mummies, including Tutankhamun’s. These results suggest avascular bone necrosis in conjunction with the malarial infection as the most likely cause of death in Tutankhamun. Walking impairment and malarial disease sustained by Tutankhamun is supported by the discovery of canes and an afterlife pharmacy in his tomb.

Conclusion Using a multidisciplinary scientific approach, we showed the feasibility of gathering data on Pharaonic kinship and diseases and speculated about individual causes of death.

King Tut may be seen as the golden boy of ancient Egypt today, but during his reign, Tutankhamun wasn't exactly a strapping sun god.

Instead, a new DNA study says, King Tut was a frail pharaoh, beset by malaria and a bone disorder—and possibly compromised by his newly discovered incestuous origins. (King Tut Pictures: DNA Study Reveals Health Secrets.)

The report is the first DNA study ever conducted with ancient Egyptian royal mummies. It apparently solves several mysteries surrounding King Tut, including how he died and who his parents were.

"He was not a very strong pharaoh. He was not riding the chariots," said study team member Carsten Pusch, a geneticist at Germany's University of Tübingen. "Picture instead a frail, weak boy who had a bit of a club foot and who needed a cane to walk."

Regarding the revelation that King Tut's mother and father were brother and sister, Pusch said, "Inbreeding is not an advantage for biological or genetic fitness. Normally the health and immune system are reduced and malformations increase," he said.

The study revealed that King Tut's parents were siblings, a trend which might have continued in Tut's marriage. "There are rumors that Tut's wife was his sister or half sister. If this is true we have at least two successive generations that had interfamilial marriages, and this is not a good thing," Pusch says. "We see it quite often in royal families that they marry each other. They thought: 'Better to stay close.' I think we cannot judge from the insight we have nowadays." Because only partial DNA was retrieved from the mummified fetuses, it is still unclear whether they were Tut's offspring or just ceremonial offerings.

In 2005 Hawass performed a computed tomography (CT) scan to determine the cause of the boy pharaoh's death. The scan revealed a fractured femur, which could have caused death from infection or from a blood clot. The present study revealed that juvenile aseptic bone necrosis—a disorder in which poor blood supply leads to bone damage—might have rendered Tut particularly vulnerable to physical injuries. "We know that this man had 130 walking sticks and that he used to shoot arrows while he was sitting," Hawass says.

But the genetic analysis identified DNA from the malaria tropica (Plasmodium falciparum) pathogen, suggesting that Tut was also hampered by infection.

Over a two-year period, until October last year, they analysed samples from 16 mummies from the royal tombs of Luxor, and used computerised tomography (CT) scans to determine whether they were related, or had genetic disorders or infectious diseases. Using genetic fingerprinting and blood group tests, the study confirms that Tutankhamun was the son of Akhenaten, the “heretical” pharaoh who tried to reform Egyptian religion and culture during his rule from 1351 to 1334BC. It also identifies some of his grandparents and great-grandparents for the first time and suggests that his mother was Akhenaten’s sister.

On the basis of other, less complete DNA evidence, Tutankhamun himself was the father of two children, both stillborn girls, whose remains were found in his tomb.

Brother-sister marriages were common in the 18th dynasty of Egypt (circa 1550 to 1295BC) but scans and genetic fingerprinting show that he suffered from several disorders as a result of his family history.

LA Times (Thomas L Maugh III)

By matching Tut's DNA to samples from other mummies, the team was able to identify one -- previously known only as KV55 -- as the pharaoh Akhenaten and the probable father of Tut; another as Tiye, Akhenaten's mother and Tut's grandmother; and a third as a sister of Akhenaten who was probably Tut's mother. . . .

"It is very important to have more empirical data about this body," said archaeologist Emily Teeter of the University of Chicago's Oriental Institute, who was not involved in the research. "The period is well documented [with artifacts] but not well understood."

She said the demonstration that Akhenaten was probably Tut's father also had "ramifications for Egyptian chronology." Researchers had not known whether Tut's father was Amenhotep III or Amenhotep IV, who took the name Akhenaten.

Science Daily

The researchers found that several of the anonymous mummies or those with suspected identities were now able to be addressed by name, which included KV35EL, who is Tiye, mother of the pharaoh Akhenaten and grandmother of Tutankhamun, and the KV55 mummy, who is most probably Akhenaten, father of Tutankhamun. This kinship is supported in that several unique anthropological features are shared by the 2 mummies and that the blood group of both individuals is identical. The researchers identified the KV35YL mummy as likely Tutankhamun's mother.

No signs of gynecomastia or Marfan syndrome were found. "Therefore, the particular artistic presentation of persons in the Amarna period is confirmed as a royally decreed style most probably related to the religious reforms of Akhenaten. It is unlikely that either Tutankhamun or Akhenaten actually displayed a significantly bizarre or feminine physique. It is important to note that ancient Egyptian kings typically had themselves and their families represented in an idealized fashion," they write.

drhawass.com (Zahi Hawass press release)

The Minister of Culture, Farouk Hosni, will hold a press conference on Wednesday, February 17, 2010 at 11:00 am in the Cairo Museum to announce new discoveries surrounding the family of Tutankhamun and the cause of the young king’s death. Reporters from around the world have been invited to attend this important event.

The study on the family of Tutankhamun was conducted through the Egyptian Mummy Project (EMP) headed by Dr. Zahi Hawass, Secretary General of the Supreme Council of Antiquities, and a team composed of Egyptian scientists from the National Research Center, members from the Faculty of Medicine at Cairo University, and two German DNA specialists.

In the past, the EMP has conducted two further studies on ancient Egyptian mummies. The first project, which was carried out in 2005, performed a CT-Scan of the mummy of Tutankhamun. The study concluded that the king had died at the age of 19, but that contrary to earlier speculation, had not been murdered by a blow to the back of the head – Egyptian scientists revealed that the hole was created during Dynasty 18 in order to insert mummification liquid. Scientists also noted that the young king suffered a fracture to his left leg a day or so before his death. The EMP’s second project succeeded in identifying the mummy of Queen Hatshepsut from among remains found in KV 60 in the Valley of the Kings. These findings have been published in scientific articles.

Dr. Zahi Hawass and the scientists involved in the EMP’s latest study submitted an article to the Journal of the American Medical Association (JAMA), who approved of the study’s scientific method. The article will be published on February 17; the same day as the press conference.

The study was conducted inside two DNA laboratories which are under the supervision of the Supreme Council of Antiquities; one is located in the basement of the Cairo Museum, and another is in the Faculty of Medicine at Cairo University. These are the only two DNA laboratories exclusively aimed at the study of ancient mummies.
