Notes

A;G

according to ClinVar this is Pathogenic, and according to HapMap it's quite rare. However it seems to be occurring in quite a few Promethease reports from healthy people. We now suspect this is being incorrectly genotyped by 23andMe, but it remains uncertain

A;A

According to ClinVar this is Pathogenic for Congenital central hypoventilation, and according to HapMap it's quite rare. However The heterozygous form seems to be occurring in quite a few Promethease reports from healthy people. We now suspect this is being incorrectly genotyped by 23andMe, but it remains uncertain. If you've found it in your promethease report info@snpedia.com would like to hear from you.
