Genes affected
CDK5RAP1 (HGNC:15880): (CDK5 regulatory subunit associated protein 1) This gene encodes a regulator of cyclin-dependent kinase 5 activity. This protein has also been reported to modify RNA by adding a methylthio-group and may thus have a dual function as an RNA methylthiotransferase and as an inhibitor of cyclin-dependent kinase 5 activity. Alternative splicing results in multiple transcript variants that encode different isoforms. [provided by RefSeq, May 2013]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 05, 2023The c.949A>G (p.S317G) alteration is located in exon 8 (coding exon 7) of the CDK5RAP1 gene. This alteration results from a A to G substitution at nucleotide position 949, causing the serine (S) at amino acid position 317 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
