Genes affected

PKD1L3 (HGNC:21716): (polycystin 1 like 3, transient receptor potential channel interacting) This gene encodes a member of the polycystin protein family. The encoded protein contains 11 transmembrane domains, a latrophilin/CL-1-like GPCR proteolytic site (GPS) domain, and a polycystin-1, lipoxygenase, alpha-toxin (PLAT) domain. This protein may function as a component of cation channel pores.[provided by RefSeq, Apr 2009]

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=0.17874953).

The c.3165G>T (p.Q1055H) alteration is located in exon 19 (coding exon 19) of the PKD1L3 gene. This alteration results from a G to T substitution at nucleotide position 3165, causing the glutamine (Q) at amino acid position 1055 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
