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=0.15403453).
BS2
High AC in GnomAd4 at 7 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 19, 2024The c.6295G>A (p.E2099K) alteration is located in exon 41 (coding exon 40) of the ASCC3 gene. This alteration results from a G to A substitution at nucleotide position 6295, causing the glutamic acid (E) at amino acid position 2099 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
