Illumina Clinical Services Laboratory,Illumina RCV000392354 SCV000432709 pathogenic Achromatopsia 2 2017-04-28 criteria provided, single submitter clinical testing The CNGA3 c.67C>T (p.Arg23Ter) stop-gained variant was reported in at least five individuals with achromatopsia or another cone dystrophy, including two homozygotes and three compound heterozygotes, and in two unaffected heterozygous parents of individuals (Johnson et al. 2004; Koeppen et al. 2008; Sundaram et al. 2014; Aboshiha et al. 2014; Zelinger et al. 2015; Huang et al. 2016). The variant was absent from six control individuals and from 100 control chromosomes. The variant is reported at a frequency of 0.00012 in the East Asian population of the Exome Aggregation Consortium, but this is based on only one allele in a region of good sequence coverage so it is presumed to be rare. Based on the evidence and due to the potential impact of stop-gained variants, the p.Arg23Ter variant is classified as pathogenic for achromatopsia. This variant was observed by ICSL as part of a predisposition screen in an ostensibly healthy population.
