Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 12, 2021The c.310G>A (p.V104M) alteration is located in exon 4 (coding exon 3) of the MTX3 gene. This alteration results from a G to A substitution at nucleotide position 310, causing the valine (V) at amino acid position 104 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
