Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 12, 2023The c.3091T>A (p.S1031T) alteration is located in exon 25 (coding exon 25) of the MAST3 gene. This alteration results from a T to A substitution at nucleotide position 3091, causing the serine (S) at amino acid position 1031 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
