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.382G>A (p.E128K) alteration is located in exon 6 (coding exon 4) of the CDKAL1 gene. This alteration results from a G to A substitution at nucleotide position 382, causing the glutamic acid (E) at amino acid position 128 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
