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]

The c.1121C>T (p.P374L) alteration is located in exon 11 (coding exon 10) of the CCAR1 gene. This alteration results from a C to T substitution at nucleotide position 1121, causing the proline (P) at amino acid position 374 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
