RCV001824809 | SCV002074146 | likely pathogenic | COG6-congenital disorder of glycosylation | 2022-01-08 | criteria provided, single submitter | clinical testing | Variant summary: COG6 c.1535T>G (p.Leu512X) results in a premature termination codon, predicted to cause a truncation of the encoded protein or absence of the protein due to nonsense mediated decay, which are commonly known mechanisms for disease. Truncations downstream of this position have not been classified as pathogenic by our laboratory but have been reported with an associated phenotype of Congenital disorder of glycosylation in the HGMD database (example, c.1843C>T, p.Gln615*). The variant allele was found at a frequency of 8e-06 in 250414 control chromosomes. To our knowledge, no occurrence of c.1535T>G in individuals affected with Congenital Disorder Of Glycosylation Type 2L and no experimental evidence demonstrating its impact on protein function have been reported. Two clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. All laboratories classified the variant as pathogenic/likely pathogenic. Based on the evidence outlined above, the variant was classified as likely pathogenic. |
