The c.318G>A (p.M106I) alteration is located in exon 6 (coding exon 4) of the SAP25 gene. This alteration results from a G to A substitution at nucleotide position 318, causing the methionine (M) at amino acid position 106 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
