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]

The c.1865C>T (p.T622I) alteration is located in exon 11 (coding exon 11) of the PKD2L1 gene. This alteration results from a C to T substitution at nucleotide position 1865, causing the threonine (T) at amino acid position 622 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
