Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 3P and 3B. PM2PP2BP4_ModerateBP6

The NM_017780.4(CHD7):c.8792T>C(p.Val2931Ala) variant causes a missense change. The variant allele was found at a frequency of 0.00000137 in 1,459,360 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 12/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. V2931M) has been classified as Likely benign.

Genes affected

CHD7 (HGNC:20626): (chromodomain helicase DNA binding protein 7) This gene encodes a protein that contains several helicase family domains. Mutations in this gene have been found in some patients with the CHARGE syndrome. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2015]

The p.V2931A variant (also known as c.8792T>C), located in coding exon 37 of the CHD7 gene, results from a T to C substitution at nucleotide position 8792. The valine at codon 2931 is replaced by alanine, an amino acid with similar properties. This amino acid position is conserved. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
