Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 16, 2024The c.364A>G (p.R122G) alteration is located in exon 5 (coding exon 4) of the MTX3 gene. This alteration results from a A to G substitution at nucleotide position 364, causing the arginine (R) at amino acid position 122 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
