Variant summary

Our verdict is Benign. Variant got -12 ACMG points: 0P and 12B. BP4_Strong BA1

The NM_181536.2(PKD1L3):​c.3528C>G​(p.Ser1176Arg) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.354 in 1,551,090 control chromosomes in the GnomAD database, including 101,518 homozygotes. In-silico tool predicts a benign outcome for this variant. 8/12 in silico tools predict a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another nucleotide change resulting in same amino acid change has been previously reported as Likely benignin UniProt.

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 Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=4.4823188E-5).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.643 is higher than 0.05.
