The c.2179G>A (p.G727S) alteration is located in exon 4 (coding exon 4) of the SPATA31D3 gene. This alteration results from a G to A substitution at nucleotide position 2179, causing the glycine (G) at amino acid position 727 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
