Variant summary

Our verdict is Uncertain significance. The variant received 3 ACMG points: 7P and 4B. PS3PP3_ModeratePP5BS2

The NM_144773.4(PROKR2):​c.563C>T​(p.Ser188Leu) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000149 in 1,614,190 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). ClinVar reports functional evidence for this variant: "SCV002521847: "Functional studies provide strong evidence of the variant having a damaging effect on the gene or gene product (PMID:18559922)."" and additional evidence is available in ClinVar. Synonymous variant affecting the same amino acid position (i.e. S188S) has been classified as Likely benign.

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: Uncertain_significance. The variant received 3 ACMG points.

PS3
PS3 evidence extracted from ClinVar submissions: SCV002521847: "Functional studies provide strong evidence of the variant having a damaging effect on the gene or gene product (PMID: 18559922)."; SCV002817207: Assessment of experimental evidence suggests this variant reduces the downstream signaling effects of this receptor, thus disrupting the normal function of the protein (PMID: 18559922, 29161432).
PP3
MetaRNN computational evidence supports a deleterious effect, 0.842
PP5
Variant 20-5302632-G-A is Pathogenic according to our data. Variant chr20-5302632-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 180158.
BS2
High AC in GnomAdExome4 at 21 AD gene.
