The c.1015A>G (p.I339V) alteration is located in exon 6 (coding exon 6) of the SLC35F3 gene. This alteration results from a A to G substitution at nucleotide position 1015, causing the isoleucine (I) at amino acid position 339 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
