Genes affected

NPY2R-AS1 (HGNC:55549): (NPY2R antisense RNA 1)

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: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.98).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.638 is higher than 0.05.
