Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 10, 2021The c.1321G>A (p.A441T) alteration is located in exon 13 (coding exon 12) of the MIGA2 gene. This alteration results from a G to A substitution at nucleotide position 1321, causing the alanine (A) at amino acid position 441 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
