The c.2754G>A (p.M918I) alteration is located in exon 4 (coding exon 4) of the SPATA31C1 gene. This alteration results from a G to A substitution at nucleotide position 2754, causing the methionine (M) at amino acid position 918 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
