Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 31, 2023The c.191G>C (p.G64A) alteration is located in exon 3 (coding exon 3) of the MTG1 gene. This alteration results from a G to C substitution at nucleotide position 191, causing the glycine (G) at amino acid position 64 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
