Hugh Reinhoff has sequenced his daughters DNA at home attempting to diagnose her unique genetic mutation. Although most parents don't have his background, he also started a website to bring together the parents of children with undiagnosed disorders, and doctors who are interested in the area. At least one family has found their answers through the community already.

Boys like trucks girl like dolls, the SSSM takes another hit

Some 25 million years ago, humans and vervet monkeys diverged from a common ancestor. In very rough terms, perhaps one and a quarter million human generations, or five million vervet generations, have been brought forth upon the Earth since that common ancestor lived. Of course, many differences have evolved between humans and vervets in those 25 million years: among other things, human parents choose toys for their children; vervet parents do not.

But after all that time and genetic change, and despite studies attributing human children's toy preferences to adult stereotypes, a new study by Dr. Gerianne Alexander finds that vervet males, like human boys, prefer toy trucks and balls, while vervet females and human girls prefer dolls and toy cooking pots. What's more, the vervets play with the toys much as human children do: males roll trucks on the ground, females inspect dolls (apparently) for genitalia.

Girl Power or: Partnership status and the human sex ratio at birth: a paper by Karen Norberg

Could the sex of a child be influenced by the status of the parents' relationship at the time of conception? In a sample of 86,436 births in the United States, we find a small excess of sons among births to parents who were married or living with an opposite sex partner before the child's conception, compared to births to parents who were not. This is the first evidence that household arrangements can affect the human sex ratio at birth, and could explain the fall in the proportion of male births in some developed countries over the past thirty years.
