Genes affected

PDK2 (HGNC:8810): (pyruvate dehydrogenase kinase 2) This gene encodes a member of the pyruvate dehydrogenase kinase family. The encoded protein phosphorylates pyruvate dehydrogenase, down-regulating the activity of the mitochondrial pyruvate dehydrogenase complex. Overexpression of this gene may play a role in both cancer and diabetes. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene.

ACMG classification

Our verdict: Benign. The variant received -19 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.22).
• BP6: Variant 17-50097524-C-A is Benign according to our data. Variant chr17-50097524-C-A is described in ClinVar as Benign. ClinVar VariationId is 777201.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BP7: Synonymous conserved (PhyloP=0.305 with no splicing effect.
• BS1: Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00602 (916/152284) while in subpopulation AFR AF = 0.0209 (870/41554). AF 95% confidence interval is 0.0198. There are 9 homozygotes in GnomAd4. There are 419 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
• BS2: High Homozygotes in GnomAd4 at 9 AR gene
