The c.1501C>T (p.R501W) alteration is located in exon 14 (coding exon 13) of the TBC1D3H gene. This alteration results from a C to T substitution at nucleotide position 1501, causing the arginine (R) at amino acid position 501 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
