Collection Method:clinical testing

The c.647A>C (p.E216A) alteration is located in exon 5 (coding exon 4) of the TBCEL gene. This alteration results from a A to C substitution at nucleotide position 647, causing the glutamic acid (E) at amino acid position 216 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
