Nov 07, 2022

The c.608A>T (p.D203V) alteration is located in exon 5 (coding exon 4) of the TBCEL gene. This alteration results from a A to T substitution at nucleotide position 608, causing the aspartic acid (D) at amino acid position 203 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
