The c.696C>G (p.I232M) alteration is located in exon 2 (coding exon 2) of the SIGLEC7 gene. This alteration results from a C to G substitution at nucleotide position 696, causing the isoleucine (I) at amino acid position 232 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
