Variant summary

Our verdict is Uncertain significance. The variant received 2 ACMG points: 2P and 0B. PM2

The ENST00000525539.5(PKD1L2):​c.1535C>A​(p.Pro512Gln) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P512T) has been classified as Uncertain significance.

Genes affected

PKD1L2 (HGNC:21715): (polycystin 1 like 2 (gene/pseudogene)) This gene encodes a member of the polycystin protein family. This protein may function as a G-protein-coupled component or regulator of cation channel pores. The long isoform of this protein contains 11 transmembrane domains, a latrophilin/CL-1-like GPCR proteolytic site (GPS) domain, and a polycystin-1, lipoxygenase, alpha-toxin (PLAT) domain. Alternative splicing results in multiple transcript variants encoding distinct isoforms. This gene is a polymorphic pseudogene in humans. [provided by RefSeq, May 2022]

ACMG classification

Our verdict: Uncertain_significance. The variant received 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
