The c.2267G>T (p.G756V) alteration is located in exon 4 (coding exon 1) of the SKIDA1 gene. This alteration results from a G to T substitution at nucleotide position 2267, causing the glycine (G) at amino acid position 756 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
