Genes affected

CCAR2 (HGNC:23360): (cell cycle and apoptosis regulator 2) Enables RNA polymerase II complex binding activity and enzyme inhibitor activity. Involved in several processes, including regulation of cellular protein metabolic process; regulation of signal transduction; and regulation of transcription, DNA-templated. Located in several cellular components, including mitochondrial matrix; nucleoplasm; and spindle. Part of DBIRD complex. [provided by Alliance of Genome Resources, Apr 2022]

The c.593A>C (p.Y198S) alteration is located in exon 8 (coding exon 7) of the CCAR2 gene. This alteration results from a A to C substitution at nucleotide position 593, causing the tyrosine (Y) at amino acid position 198 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
