Notes
c.4563_4564delAT (p.Leu1522Glyfs)
-;AT
See details via ClinVar link on main SNP/rs# page.
D;D
The common genotype should be (I;I), but Ancestry appears to tell ~100% of their users that they are (D;D), so for Ancestry users, this genotype is the common/normal one.
D;I
In theory, this is rs483353115(-;AT) however our statistics indicate this is prone to being miscalled on the Ancestry.com platform. If it's real then these guidelines apply.
