This variant has also been identified in 0.036% (6/16,458) of S outh Asian chromosomes by the Exome Aggregation Consortium (ExAC,; dbSNP rs104893621). Although this variant has been seen in the general population, its frequency is low enough to be consistent with a recessi ve carrier frequency. In summary, this variant meets criteria to be classified a s pathogenic for CNGA3-related achromatopsia/ cone-rod dystrophy in an autosomal recessive manner based upon its biallelic occurrence in affected individuals an d low frequency in control populations.
