Ambry Genetics | RCV002360536 | SCV002665329 | uncertain significance | Inborn genetic diseases | 2018-01-24 | criteria provided, single submitter | clinical testing | The c.6989_6990delGCinsCT variant (also known as p.G2330A), located in coding exon 32 of the CHD7 gene, results from an in-frame deletion of GC and insertion of CT at nucleotide positions 6989 to 6990. This results in the substitution of the glycine residue for an alanine residue at codon 2330, an amino acid with similar properties. In one study, c.6989G>C (p.G2330A) was reported as a rare missense variation of unknown pathogenicity identified in a cohort of samples submitted for CHD7 analysis (Bartels CF et al. Genet Test Mol Biomarkers, 2010 Dec;14:881-91). In another study, c.6989G>C (p.G2330A) was classified as a benign CHD7 missense variant present in two or more controls and/or found in the homozygous state; however, more specific information was not provided (Bergman JE et al. Hum. Mutat., 2012 Aug;33:1251-60). This amino acid position is highly conserved in available vertebrate species. Based on available evidence to date, the clinical significance of this alteration remains unclear. |
