The c.751C>T (p.R251W) alteration is located in exon 12 (coding exon 11) of the TPTE2 gene. This alteration results from a C to T substitution at nucleotide position 751, causing the arginine (R) at amino acid position 251 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
