Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 25, 2022The c.1139C>T (p.S380F) alteration is located in exon 2 (coding exon 2) of the MAML3 gene. This alteration results from a C to T substitution at nucleotide position 1139, causing the serine (S) at amino acid position 380 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
