Genes affected

TRPC5 (HGNC:12337): (transient receptor potential cation channel subfamily C member 5) This gene belongs to the transient receptor family. It encodes one of the seven mammalian TRPC (transient receptor potential channel) proteins. The encoded protein is a multi-pass membrane protein and is thought to form a receptor-activated non-selective calcium permeant cation channel. The protein is active alone or as a heteromultimeric assembly with TRPC1, TRPC3, and TRPC4. It also interacts with multiple proteins including calmodulin, CABP1, enkurin, Na(+)-H+ exchange regulatory factor (NHERF ), interferon-induced GTP-binding protein (MX1), ring finger protein 24 (RNF24), and SEC14 domain and spectrin repeat-containing protein 1 (SESTD1).

Ambry Genetics

Apr 06, 2023

The c.2503C>T (p.R835C) alteration is located in exon 11 (coding exon 10) of the TRPC5 gene. This alteration results from a C to T substitution at nucleotide position 2503, causing the arginine (R) at amino acid position 835 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
