Genes affected
ANGPTL3 (HGNC:491): (angiopoietin like 3) This gene encodes a member of a family of secreted proteins that function in angiogenesis. The encoded protein, which is expressed predominantly in the liver, is further processed into an N-terminal coiled-coil domain-containing chain and a C-terminal fibrinogen chain. The N-terminal chain is important for lipid metabolism, while the C-terminal chain may be involved in angiogenesis. Mutations in this gene cause familial hypobetalipoproteinemia type 2. [provided by RefSeq, Aug 2015]
DOCK7 (HGNC:19190): (dedicator of cytokinesis 7) The protein encoded by this gene is a guanine nucleotide exchange factor (GEF) that plays a role in axon formation and neuronal polarization. The encoded protein displays GEF activity toward RAC1 and RAC3 Rho small GTPases but not toward CDC42. Several transcript variants encoding different isoforms have been found for this gene.

The c.217C>A (p.Q73K) alteration is located in exon 1 (coding exon 1) of the ANGPTL3 gene. This alteration results from a C to A substitution at nucleotide position 217, causing the glutamine (Q) at amino acid position 73 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
