Genes affected

CCAR1 (HGNC:24236): (cell division cycle and apoptosis regulator 1) Enables RNA polymerase II cis-regulatory region sequence-specific DNA binding activity; nuclear receptor coactivator activity; and transcription corepressor activity. Involved in positive regulation of cell migration and positive regulation of cell population proliferation. Acts upstream of or within positive regulation of apoptotic process. Located in nuclear envelope lumen. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant where missense usually causes diseases, CCAR1
• BP4: Computational evidence support a benign effect (MetaRNN=0.21021649).

The c.2632G>T (p.A878S) alteration is located in exon 19 (coding exon 18) of the CCAR1 gene. This alteration results from a G to T substitution at nucleotide position 2632, causing the alanine (A) at amino acid position 878 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
