chr8-60851085-C-T

Variant summary

Our verdict is Likely benign. Variant got -3 ACMG points: 2P and 5B. PP2PP5BP4BS2

The NM_017780.4(CHD7):​c.5588C>T​(p.Pro1863Leu) variant causes a missense change. The variant allele was found at a frequency of 0.000035 in 1,571,822 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 Lovd as Likely pathogenic (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P1863Q) 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 Likely_benign. Variant got -3 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.
PP5
Variant 8-60851085-C-T is Pathogenic according to our data. Variant chr8-60851085-C-T is described in Lovd as [Likely_pathogenic].
BP4
Computational evidence support a benign effect (MetaRNN=0.09429976). . Strength limited to SUPPORTING due to the PP5.
BS2
High AC in GnomAd4 at 7 AD gene.
