Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 06, 2023The c.2984C>T (p.A995V) alteration is located in exon 24 (coding exon 24) of the MAST3 gene. This alteration results from a C to T substitution at nucleotide position 2984, causing the alanine (A) at amino acid position 995 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
