The c.1096G>C (p.G366R) alteration is located in exon 2 (coding exon 1) of the B3GNT9 gene. This alteration results from a G to C substitution at nucleotide position 1096, causing the glycine (G) at amino acid position 366 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
