Ambry Genetics

Jul 05, 2023

The c.425T>A (p.L142Q) alteration is located in exon 3 (coding exon 3) of the TMC7 gene. This alteration results from a T to A substitution at nucleotide position 425, causing the leucine (L) at amino acid position 142 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
