Genes affected

PKD2L1 (HGNC:9011): (polycystin 2 like 1, transient receptor potential cation channel) This gene encodes a member of the polycystin protein family. The encoded protein contains multiple transmembrane domains, and cytoplasmic N- and C-termini. The protein may be an integral membrane protein involved in cell-cell/matrix interactions. This protein functions as a calcium-regulated nonselective cation channel. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2011]

Ambry Genetics

Nov 03, 2023

The c.2140G>T (p.V714F) alteration is located in exon 14 (coding exon 14) of the PKD2L1 gene. This alteration results from a G to T substitution at nucleotide position 2140, causing the valine (V) at amino acid position 714 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
