Genes affected

ASCC3 (HGNC:18697): (activating signal cointegrator 1 complex subunit 3) This gene encodes a protein that belongs to a family of helicases that are involved in the ATP-dependent unwinding of nucleic acid duplexes. The encoded protein is the largest subunit of the activating signal cointegrator 1 complex that is involved in DNA repair and resistance to alkylation damage. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Sep 2013]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -2 ACMG points.

PP2

Missense variant in gene, where missense usually causes diseases (based on misZ statistic), ASCC3. . Gene score misZ 2.2287 (greater than the threshold 3.09). Trascript score misZ 3.3318 (greater than threshold 3.09). GenCC has associacion of gene with intellectual disability.

BP4

Computational evidence support a benign effect (MetaRNN=0.07986173).

BS2

High AC in GnomAd4 at 6 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.

The c.5834A>G (p.N1945S) alteration is located in exon 38 (coding exon 37) of the ASCC3 gene. This alteration results from a A to G substitution at nucleotide position 5834, causing the asparagine (N) at amino acid position 1945 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
