The c.829G>C (p.V277L) alteration is located in exon 3 (coding exon 3) of the TRPC7 gene. This alteration results from a G to C substitution at nucleotide position 829, causing the valine (V) at amino acid position 277 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
