Jun 14, 2023

The c.279T>G (p.C93W) alteration is located in exon 4 (coding exon 4) of the MTBP gene. This alteration results from a T to G substitution at nucleotide position 279, causing the cysteine (C) at amino acid position 93 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
