not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 11, 2024The c.386C>A (p.T129N) alteration is located in exon 6 (coding exon 6) of the MTA3 gene. This alteration results from a C to A substitution at nucleotide position 386, causing the threonine (T) at amino acid position 129 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
