The c.265G>A (p.G89S) alteration is located in exon 3 (coding exon 3) of the SUN3 gene. This alteration results from a G to A substitution at nucleotide position 265, causing the glycine (G) at amino acid position 89 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
