Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 22, 2023The c.554C>A (p.A185D) alteration is located in exon 7 (coding exon 7) of the MTG1 gene. This alteration results from a C to A substitution at nucleotide position 554, causing the alanine (A) at amino acid position 185 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
