Genes affected

PKD1L1 (HGNC:18053): (polycystin 1 like 1, transient receptor potential channel interacting) This gene encodes a member of the polycystin protein family containing 11 transmembrane domains, a receptor for egg jelly (REJ) domain, and a polycystin-1, lipoxygenase, alpha-toxin (PLAT) domain. The encoded protein may play a role in the male reproductive system. Alternative splice variants have been described but their biological nature has not been determined.

PKD1L1-AS1 (HGNC:21911): (PKD1L1 antisense RNA 1) Predicted to be located in extracellular region. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.10569137).
