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.

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -5 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.04687527).

BS1

Variant frequency is greater than expected in population eas. gnomad4_exome allele frequency = 0.00000889 (13/1461632) while in subpopulation EAS AF= 0.000302 (12/39696). AF 95% confidence interval is 0.000173. There are 1 homozygotes in gnomad4_exome. There are 11 alleles in male gnomad4_exome subpopulation. Median coverage is 35. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The cysteine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. This variant has not been reported in the literature in individuals affected with SLC39A14-related conditions. This variant is present in population databases (rs183988980, ExAC 0.01%). This sequence change replaces glycine with cysteine at codon 20 of the SLC39A14 protein (p.Gly20Cys). The glycine residue is weakly conserved and there is a large physicochemical difference between glycine and cysteine. -
