Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 05, 2021The c.1501A>G (p.T501A) alteration is located in exon 11 (coding exon 10) of the MAP9 gene. This alteration results from a A to G substitution at nucleotide position 1501, causing the threonine (T) at amino acid position 501 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
