rs74315329, also known as Q168X and Gln368Ter, is a nonsense mutation in the MYOC gene on chromosome 1. 23andMe name: i5007108

The rs74315329(T) allele (in dbSNP orientation) has been reported to be a pathogenic autosomal dominant mutation leading to primary open angle glaucoma with either early-onset or juvenile onset.ClinVar

However, other reports indicate that inheritance does not follow a simple dominant model ([PMID 11535458]), and full sequencing has incidentally uncovered several adults who harbor this mutation yet who lack a significant family history and also do not show show signs of glaucoma, at least at the time of examination.[PMID 26046366OA-icon.png]

The penetrance of the variant varies in different scenarios.[PMID 30267046OA-icon.png]

A polygenic risk score influencing the likelihood of glaucoma progression in Q168X carriers (and possibly others) was published in 2020.[PMID 31959993OA-icon.png]
