RCV000757371 | SCV000885567 | uncertain significance | not provided | 2018-02-02 | criteria provided, single submitter | clinical testing | The HEXA c.1337C>G; p.Pro446Arg variant, to our knowledge, is not reported in the medical literature, gene specific variation databases, nor has it been previously identified by our laboratory. This variant is absent from the general population databases (1000 Genomes Project, Exome Variant Server, Genome Aggregation Database), indicating it is not a common polymorphism. The proline at position 446 is moderately conserved, considering 12 species, and computational analyses of the effects of the p.Pro446Arg variant on protein structure and function do not predict a deleterious effect (SIFT: tolerated, MutationTaster: polymorphism, PolyPhen-2: benign). Based on the available information, the clinical significance of the p.Pro446Arg variant cannot be determined with certainty. |
