Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 08, 2024The c.325A>G (p.N109D) alteration is located in exon 3 (coding exon 3) of the MZT2B gene. This alteration results from a A to G substitution at nucleotide position 325, causing the asparagine (N) at amino acid position 109 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
