The c.342G>T (p.W114C) alteration is located in exon 4 (coding exon 4) of the MFSD4B gene. This alteration results from a G to T substitution at nucleotide position 342, causing the tryptophan (W) at amino acid position 114 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
