Variant summary

Our verdict is Benign. Variant got -8 ACMG points: 1P and 9B. PP2BP4_StrongBP6BS2

The NM_017780.4(CHD7):​c.7085G>A​(p.Ser2362Asn) variant causes a missense change. The variant allele was found at a frequency of 0.0000714 in 1,610,066 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). Synonymous variant affecting the same amino acid position (i.e. S2362S) 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]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -8 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=0.045812756).
BP6
Variant 8-60856123-G-A is Benign according to our data. Variant chr8-60856123-G-A is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 95809.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=4, Uncertain_significance=3}. Variant chr8-60856123-G-A is described in Lovd as [Likely_benign].
BS2
High AC in GnomAd4 at 34 AD gene.

Likely benign, criteria provided, single submitterclinical testingAmbry GeneticsSep 21, 2017This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
