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.

ACMG classification
Classification made for transcript
Verdict is Likely_pathogenic. Variant got 9 ACMG points.
PM2
Very rare variant in population databases, with high coverage;
PP5
Variant 19-48965348-A-G is Pathogenic according to our data. Variant chr19-48965348-A-G is described in ClinVar as [Pathogenic]. Clinvar id is 16474.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr19-48965348-A-G is described in Lovd as [Pathogenic].
BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.14). . Strength limited to SUPPORTING due to the PP5.

Hereditary hyperferritinemia with congenital cataracts;C1853578:Neuroferritinopathy Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Jan 16, 2024 | This variant occurs in a non-coding region of the FTL gene. It does not change the encoded amino acid sequence of the FTL protein. This variant is not present in population databases (gnomAD no frequency). This variant has been observed in individuals with hereditary hyperferritinemia and cataract syndrome (PMID: 7493028, 11703332, 14662596, 24766965, 30401656). It has also been observed to segregate with disease in related individuals. This variant is also known as A40G. ClinVar contains an entry for this variant (Variation ID: 16474). Algorithms developed to predict the effect of variants on protein structure and function are not available or were not evaluated for this variant. Experimental studies have shown that this variant affects FTL function (PMID: 7493028). For these reasons, this variant has been classified as Pathogenic. - |
