Illumina Laboratory Services, Illumina RCV000303034 SCV000398959 pathogenic Macular corneal dystrophy 2017-04-27 criteria provided, single submitter clinical testing The CHST6 c.892C>T (p.Gln298Ter) variant is a stop-gained variant that is predicted to result in a premature termination of the protein. The p.Gln298Ter variant has been reported in two studies in which it is found in a total of 11 patients with macular corneal dystrophy, including in two from the same family in a homozygous state, in nine in a compound heterozygous state (at least three of whom are related), and in a heterozygous state in three unaffected family members (Dang et al. 2009; Liu et al. 2010). The p.Gln298Ter variant was absent from 150 controls and is not found in the 1000 Genomes Project, the Exome Sequencing Project, or the Exome Aggregation Consortium. Based on the evidence and the potential impact of stop-gained variants, the p.Gln298Ter variant is classified as pathogenic for macular corneal dystrophy. This variant was observed by ICSL as part of a predisposition screen in an ostensibly healthy population.
