Genes affected

CDKAL1 (HGNC:21050): (CDK5 regulatory subunit associated protein 1 like 1) The protein encoded by this gene is a member of the methylthiotransferase family. The function of this gene is not known. Genome-wide association studies have linked single nucleotide polymorphisms in an intron of this gene with susceptibilty to type 2 diabetes. [provided by RefSeq, May 2010]

The c.1410C>A (p.F470L) alteration is located in exon 15 (coding exon 13) of the CDKAL1 gene. This alteration results from a C to A substitution at nucleotide position 1410, causing the phenylalanine (F) at amino acid position 470 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
