Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 22, 2022The c.15T>G (p.D5E) alteration is located in exon 1 (coding exon 1) of the VMA21 gene. This alteration results from a T to G substitution at nucleotide position 15, causing the aspartic acid (D) at amino acid position 5 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
not specified Benign:1
Likely benign, criteria provided, single submitterclinical testingGeneDxJul 22, 2016This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. -
VMA21-related disorder Benign:1
