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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 06, 2021The c.550C>T (p.R184W) alteration is located in exon 7 (coding exon 6) of the CCAR2 gene. This alteration results from a C to T substitution at nucleotide position 550, causing the arginine (R) at amino acid position 184 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
