Genes affected

PROKR2 (HGNC:15836): (prokineticin receptor 2) Prokineticins are secreted proteins that can promote angiogenesis and induce strong gastrointestinal smooth muscle contraction. The protein encoded by this gene is an integral membrane protein and G protein-coupled receptor for prokineticins. The encoded protein is similar in sequence to GPR73, another G protein-coupled receptor for prokineticins. [provided by RefSeq, Jul 2008]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 1 ACMG points.

PM4

Stoplost variant in NM_144773.4 Downstream stopcodon found after 53 codons.

BS1

Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.000217 (33/152268) while in subpopulation AFR AF= 0.000746 (31/41554). AF 95% confidence interval is 0.000539. There are 0 homozygotes in gnomad4. There are 18 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
