The c.47A>C (p.K16T) alteration is located in exon 1 (coding exon 1) of the TBC1D12 gene. This alteration results from a A to C substitution at nucleotide position 47, causing the lysine (K) at amino acid position 16 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
