The c.676C>T (p.R226C) alteration is located in exon 4 (coding exon 4) of the GIPC2 gene. This alteration results from a C to T substitution at nucleotide position 676, causing the arginine (R) at amino acid position 226 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
