Genes affected

TRPC4 (HGNC:12336): (transient receptor potential cation channel subfamily C member 4) This gene encodes a member of the canonical subfamily of transient receptor potential cation channels. The encoded protein forms a non-selective calcium-permeable cation channel that is activated by Gq-coupled receptors and tyrosine kinases, and plays a role in multiple processes including endothelial permeability, vasodilation, neurotransmitter release and cell proliferation. Single nucleotide polymorphisms in this gene may be associated with generalized epilepsy with photosensitivity. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Aug 2011]

The c.830T>C (p.L277P) alteration is located in exon 3 (coding exon 2) of the TRPC4 gene. This alteration results from a T to C substitution at nucleotide position 830, causing the leucine (L) at amino acid position 277 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
