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]

Dec 21, 2023

The c.2202G>T (p.K734N) 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 2202, causing the lysine (K) at amino acid position 734 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
