Genes affected

NPY2R (HGNC:7957): (neuropeptide Y receptor Y2) Predicted to enable calcium channel regulator activity and neuropeptide Y receptor activity. Involved in cardiac left ventricle morphogenesis and outflow tract morphogenesis. Located in cilium. Implicated in Huntington's disease; morbid obesity; and obesity. Biomarker of peripheral artery disease and temporal lobe epilepsy. [provided by Alliance of Genome Resources, Apr 2022]

MAP9-AS1 (HGNC:56110): (MAP9 antisense RNA 1)

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 (MetaRNN=0.06147322).
