Collection Method: clinical testing

The c.941A>G (p.E314G) alteration is located in exon 7 (coding exon 6) of the TBCEL gene. This alteration results from a A to G substitution at nucleotide position 941, causing the glutamic acid (E) at amino acid position 314 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
