This variant was found in 889/113020 control chromosomes from ExAC (including 28 homozygotes), predominantly observed in the East Asian subpopulation at a frequency of 0.066619 (558/8376). This frequency is about 15 times the estimated maximal expected allele frequency of a pathogenic DHCR7 variant (0.0043301), suggesting this is likely a benign polymorphism found primarily in the populations of East Asian origin. At least one clinical diagnostic laboratory in ClinVar has classified this variant as benign. The variant of interest has not, to our knowledge, been reported in affected individuals via publications. Taken together, this variant is classified as Benign.
