Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 13, 2024The c.1386G>A (p.M462I) alteration is located in exon 2 (coding exon 2) of the MAML3 gene. This alteration results from a G to A substitution at nucleotide position 1386, causing the methionine (M) at amino acid position 462 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
