The c.806T>C (p.I269T) alteration is located in exon 5 (coding exon 5) of the SLC35F4 gene. This alteration results from a T to C substitution at nucleotide position 806, causing the isoleucine (I) at amino acid position 269 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
