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]

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.58).
BP6
Variant 20-5302073-G-T is Benign according to our data. Variant chr20-5302073-G-T is described in ClinVar as Benign. ClinVar VariationId is 338851.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BP7
Synonymous conserved (PhyloP=1.79 with no splicing effect.
BS1
Variant frequency is greater than expected in population sas. GnomAd4 allele frequency = 0.00217 (331/152244) while in subpopulation SAS AF = 0.0339 (163/4814). AF 95% confidence interval is 0.0296. There are 4 homozygotes in GnomAd4. There are 213 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.
BS2
High AC in GnomAd4 at 331 AD gene.
