The c.296T>C (p.I99T) alteration is located in exon 3 (coding exon 3) of the MFSD4B gene. This alteration results from a T to C substitution at nucleotide position 296, causing the isoleucine (I) at amino acid position 99 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
