The c.133C>T (p.R45W) alteration is located in exon 2 (coding exon 2) of the TGM4 gene. This alteration results from a C to T substitution at nucleotide position 133, causing the arginine (R) at amino acid position 45 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
