Variant summary

Our verdict is Benign. Variant got -13 ACMG points: 1P and 14B. PP2BP4_ModerateBP6_Very_StrongBS2

The NM_017780.4(CHD7):ā€‹c.1672C>Gā€‹(p.Pro558Ala) variant causes a missense change. The variant allele was found at a frequency of 0.0000239 in 1,549,408 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (ā˜…ā˜…). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P558L) has been classified as Uncertain significance.

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 -13 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=0.21068847).
BP6
Variant 8-60781006-C-G is Benign according to our data. Variant chr8-60781006-C-G is described in ClinVar as [Likely_benign]. Clinvar id is 570104.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BS2
High AC in GnomAd4 at 11 AD gene.
