Genes affected

SLC30A10 (HGNC:25355): (solute carrier family 30 member 10) This gene is highly expressed in the liver and is inducible by manganese. Its protein product appears to be critical in maintaining manganese levels, and has higher specificity for manganese than zinc. Loss of function mutations appear to result in a pleomorphic phenotype, including dystonia and adult-onset parkinsonism. Alternatively spliced transcript variants have been observed for this gene.

The variant is not observed in the gnomAD v2.1.1 dataset. In silico tool predictions suggest damaging effect of the variant on gene or gene product (REVEL: 0.60; 3Cnet: 0.47). Same nucleotide change resulting in same amino acid change has been previously reported to be associated with SLC30A10 -related disorder (ClinVar ID: VCV000375609 / PMID: 27117033). However, the evidence of pathogenicity is insufficient at this time. Therefore, this variant is classified as uncertain significance according to the recommendation of ACMG/AMP guideline.
