The c.358C>T (p.R120W) alteration is located in exon 2 (coding exon 1) of the TBC1D14 gene. This alteration results from a C to T substitution at nucleotide position 358, causing the arginine (R) at amino acid position 120 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
