Mar 21, 2022

The c.1027A>G (p.T343A) alteration is located in exon 7 (coding exon 6) of the MAP9 gene. This alteration results from a A to G substitution at nucleotide position 1027, causing the threonine (T) at amino acid position 343 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
