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 Likely_benign. Variant got -5 ACMG points.

PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), CHD7. . Gene score misZ 3.2193 (greater than the threshold 3.09). Trascript score misZ 3.9401 (greater than threshold 3.09). GenCC has associacion of gene with Kallmann syndrome, hypogonadotropic hypogonadism 5 with or without anosmia, CHARGE syndrome, hypogonadotropic hypogonadism, Omenn syndrome.
BP4
Computational evidence support a benign effect (MetaRNN=0.2646609).
BP6
Variant 8-60852201-G-A is Benign according to our data. Variant chr8-60852201-G-A is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 196181.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=3, Uncertain_significance=1}. Variant chr8-60852201-G-A is described in Lovd as [Likely_benign].
BS2
