Collection Method: clinical testing

The c.1352G>A (p.S451N) alteration is located in exon 10 (coding exon 9) of the MAP9 gene. This alteration results from a G to A substitution at nucleotide position 1352, causing the serine (S) at amino acid position 451 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
