The c.2444A>G (p.D815G) alteration is located in exon 12 (coding exon 12) of the TRPC7 gene. This alteration results from a A to G substitution at nucleotide position 2444, causing the aspartic acid (D) at amino acid position 815 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
