The c.632C>G (p.S211C) alteration is located in exon 8 (coding exon 7) of the IZUMO1 gene. This alteration results from a C to G substitution at nucleotide position 632, causing the serine (S) at amino acid position 211 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
