Ambry Genetics

Dec 21, 2022

The c.2050C>T (p.R684W) 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 2050, causing the arginine (R) at amino acid position 684 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
