Genes affected

CMKLR2 (HGNC:4463): (chemerin chemokine-like receptor 2) Enables adipokinetic hormone binding activity and adipokinetic hormone receptor activity. Predicted to be involved in glucose homeostasis and neuropeptide signaling pathway. Located in nucleoplasm and plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

CMKLR2-AS (HGNC:48602): (CMKLR2 antisense RNA) This gene is thought to produce a non-coding RNA. It is situated adjacent to a differentially methylated region (DMR) and is imprinted and paternally expressed in the placenta. [provided by RefSeq, Nov 2015]

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.84).
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.0973 is higher than 0.05.
