Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 10, 2021The c.1298T>G (p.V433G) alteration is located in exon 3 (coding exon 2) of the MGA gene. This alteration results from a T to G substitution at nucleotide position 1298, causing the valine (V) at amino acid position 433 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
