Genes affected

SAMD14 (HGNC:27312): (sterile alpha motif domain containing 14) Predicted to enable actin filament binding activity. Predicted to be involved in actin filament organization; calcium-mediated signaling; and neuron projection development. Predicted to be active in several cellular components, including actin cytoskeleton; dendrite; and postsynaptic density. [provided by Alliance of Genome Resources, Apr 2022]

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: Likely_benign. The variant received -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.91).
