The c.1988C>T (p.T663M) alteration is located in exon 11 (coding exon 10) of the TBC1D16 gene. This alteration results from a C to T substitution at nucleotide position 1988, causing the threonine (T) at amino acid position 663 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
