(C;G) 3 Carrier of a Tay-Sachs mutation
(G;G) 0 common in clinvar

This genotype should be extremely rare, representing a Tay-Sachs disease genotype (with two copies of an extremely rare mutation), but it is very commonly reported incorrectly in Ancestry raw data files and is therefore almost 100% certain to be a miscall if seen in your report (and, in reality, you have the completely common, normal genotype for this SNP).
