The c.3079T>G (p.W1027G) alteration is located in exon 6 (coding exon 6) of the SYDE2 gene. This alteration results from a T to G substitution at nucleotide position 3079, causing the tryptophan (W) at amino acid position 1027 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
