The c.856C>A (p.R286S) alteration is located in exon 9 (coding exon 9) of the B3GNTL1 gene. This alteration results from a C to A substitution at nucleotide position 856, causing the arginine (R) at amino acid position 286 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
