The c.2564G>A (p.R855K) alteration is located in exon 12 (coding exon 12) of the TRPC7 gene. This alteration results from a G to A substitution at nucleotide position 2564, causing the arginine (R) at amino acid position 855 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
