Broader Autism Phenotype

I came across this phrase today when I was raking pubmed for hits on progesterone and the brain. Well, first I'll post the link to an article about progesterone and autism: http://www.ncbi.nlm.nih.gov/pubmed/24485701 And here's an article from the 90's discussing BAP. http://ajp.psychiatryonline.org/data/Journals/AJP/3673/185.pdf The 90's is a long time ago, so I'm not sure if BAP is considered a thing or not. I guess I'll ask my sister.
