The c.848C>T (p.A283V) alteration is located in exon 4 (coding exon 3) of the FUT10 gene. This alteration results from a C to T substitution at nucleotide position 848, causing the alanine (A) at amino acid position 283 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
