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 was made for transcript

Our verdict: Benign. The variant received -20 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.00956881).

BP6

Variant 20-5302204-C-T is Benign according to our data. Variant chr20-5302204-C-T is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 338854.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BS1

Variant frequency is greater than expected in population sas. GnomAd4 allele frequency = 0.00221 (336/152308) while in subpopulation SAS AF = 0.0338 (163/4818). AF 95% confidence interval is 0.0296. There are 3 homozygotes in GnomAd4. There are 216 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.

BS2

High AC in GnomAd4 at 336 AD gene.
