Genes affected
FTL (HGNC:3999): (ferritin light chain) This gene encodes the light subunit of the ferritin protein. Ferritin is the major intracellular iron storage protein in prokaryotes and eukaryotes. It is composed of 24 subunits of the heavy and light ferritin chains. Variation in ferritin subunit composition may affect the rates of iron uptake and release in different tissues. A major function of ferritin is the storage of iron in a soluble and nontoxic state. Defects in this light chain ferritin gene are associated with several neurodegenerative diseases and hyperferritinemia-cataract syndrome. This gene has multiple pseudogenes.

Uncertain significance, criteria provided, single submitterclinical testingGeneDxApr 26, 2022Nucleotide substitution has no predicted effect on splicing and is not conserved across species; Has not been previously published as pathogenic or benign to our knowledge; No data available from ethnically-matched control populations to assess the frequency of this variant; The variant occurs in a regulatory region and is not expected to create a new ATG initiation codon, however, in the absence of RNA/functional studies, the actual effect of the variant in this individual is uncertain. -
