Notes

rs964201 is an A/G SNP located in the ASPM gene. The G-allele of this SNP as well as the A-allele of rs3762271 another SNP located in the ASPM gene and rs2442496 a SNP in the MCPH1 gene arose approximately 50,000 years ago and show strong positive selection in the lineage leading to humans. A comment is found at g2b2mh.

A;A

clinvar thinks this is the reference, but hapmap data seems to consider 'A' as a very minor allele
