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]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.89).
• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.0172 (2619/152304) while in subpopulation NFE AF= 0.0246 (1674/68018). AF 95% confidence interval is 0.0236. There are 34 homozygotes in gnomad4. There are 1288 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 34 gene
