Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 08, 2023The c.55G>A (p.A19T) alteration is located in exon 3 (coding exon 2) of the MTX3 gene. This alteration results from a G to A substitution at nucleotide position 55, causing the alanine (A) at amino acid position 19 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
