Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 17, 2021The c.1270A>T (p.I424L) alteration is located in exon 9 (coding exon 8) of the MAP9 gene. This alteration results from a A to T substitution at nucleotide position 1270, causing the isoleucine (I) at amino acid position 424 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
