Genes affected
CDK5RAP3 (HGNC:18673): (CDK5 regulatory subunit associated protein 3) This gene encodes a protein that has been reported to function in signaling pathways governing transcriptional regulation and cell cycle progression. It may play a role in tumorigenesis and metastasis. A pseudogene of this gene is located on the long arm of chromosome 20. Alternative splicing results in multiple transcript variants that encode different isoforms. [provided by RefSeq, May 2013]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 22, 2023The c.797C>T (p.A266V) alteration is located in exon 8 (coding exon 8) of the CDK5RAP3 gene. This alteration results from a C to T substitution at nucleotide position 797, causing the alanine (A) at amino acid position 266 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
