GeneDx RCV000421294 SCV000530558 uncertain significance not provided 2017-01-19 criteria provided, single submitter clinical testing The V781M variant in the GNPTAB gene has been reported previously in an individual with stuttering, however it has not been seen in any cases of mucolipidosis (Raza et al., 2015). The V781M variant was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. The V781M variant is a conservative amino acid substitution, which is not likely to impact secondary protein structure as these residues share similar properties. This substitution occurs at a position that is not conserved. In silico analysis is inconsistent in its predictions as to whether or not the variant is damaging to the protein structure/function. We interpret V781M as a variant of uncertain significance.
Illumina Laboratory Services, Illumina RCV001114039 SCV001271866 uncertain significance Mucolipidosis type II 2017-04-28 criteria provided, single submitter clinical testing This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases did not allow this variant to be ruled in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance.
Illumina Laboratory Services, Illumina RCV001114040 SCV001271867 uncertain significance Pseudo-Hurler polydystrophy 2017-04-28 criteria provided, single submitter clinical testing This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases did not allow this variant to be ruled in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance.
