Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 19, 2023The c.2722G>A (p.A908T) alteration is located in exon 22 (coding exon 22) of the MAST3 gene. This alteration results from a G to A substitution at nucleotide position 2722, causing the alanine (A) at amino acid position 908 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
