Variant summary

Our verdict is Likely benign. Variant got -3 ACMG points: 2P and 5B. PM2 BP4_Strong BP7

The NM_000910.4(NPY2R):​c.654C>T​(p.Val218Val) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000657 in 152,182 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Synonymous variant affecting the same amino acid position (i.e. V218V) has been classified as Benign.

• Frequency: Genomes: 𝑓 0.0000066 (0 hom., cov: 33)
• Consequence: NPY2R NM_000910.4 synonymous
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 0.686

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

Verdict is Likely_benign. Variant got -3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.48).
• BP7: Synonymous conserved (PhyloP=0.686 with no splicing effect.
