Ambry Genetics

Aug 28, 2023

The c.1261G>A (p.A421T) alteration is located in exon 9 (coding exon 8) of the MAP9 gene. This alteration results from a G to A substitution at nucleotide position 1261, causing the alanine (A) at amino acid position 421 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
