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]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 2 ACMG points.

PM1
In a domain Helicase ATP-binding (size 174) in uniprot entity CHD7_HUMAN there are 15 pathogenic changes around while only 1 benign (94%) in NM_017780.4
PM2
Very rare variant in population databases, with high coverage;
BP4
Computational evidence support a benign effect (MetaRNN=0.35338268).
BP6
Variant 8-60822575-A-G is Benign according to our data. Variant chr8-60822575-A-G is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 529125.We mark this variant Likely_benign, oryginal submissions are: {Uncertain_significance=1, Likely_benign=1}.
