Ambry Genetics

Dec 02, 2022

The c.256G>A (p.A86T) alteration is located in exon 6 (coding exon 4) of the SUPT3H gene. This alteration results from a G to A substitution at nucleotide position 256, causing the alanine (A) at amino acid position 86 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
