Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 17, 2023The c.2813G>A (p.R938Q) alteration is located in exon 23 (coding exon 23) of the MAST3 gene. This alteration results from a G to A substitution at nucleotide position 2813, causing the arginine (R) at amino acid position 938 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
