Genes affected

SLC39A14 (HGNC:20858): (solute carrier family 39 member 14) This gene encodes a member of the the SLC39A family of divalent metal transporters that mediates the cellular uptake of manganese, zinc, iron, and cadmium. The encoded protein contains eight transmembrane domains, a histidine-rich motif, and a metalloprotease motif, and is expressed on the plasma membrane and the endocytic vesicle membrane. It is an important transporter of nontransferrin-bound iron and a critical regulator of manganese homeostasis. Naturally occurring mutations in this gene are associated with neurodegeneration with brain iron accumulation and early-onset parkinsonism-dystonia with hypermanganesemia.

The c.26C>T (p.A9V) alteration is located in exon 2 (coding exon 1) of the SLC39A14 gene. This alteration results from a C to T substitution at nucleotide position 26, causing the alanine (A) at amino acid position 9 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
