Genes affected

FLG (HGNC:3748): (filaggrin) The protein encoded by this gene is an intermediate filament-associated protein that aggregates keratin intermediate filaments in mammalian epidermis. It is initially synthesized as a polyprotein precursor, profilaggrin (consisting of multiple filaggrin units of 324 aa each), which is localized in keratohyalin granules, and is subsequently proteolytically processed into individual functional filaggrin molecules. Mutations in this gene are associated with ichthyosis vulgaris.[provided by RefSeq, Dec 2009]

The FLG c.3702del (p.Ser1235HisfsTer211) variant, also known as 3702delG, has been described in the heterozygous and compound heterozygous state in individuals affected with atopic dermatitis or icthyosis vulgaris and is associated with an increased risk for atopic dermatitis (OR 7.9; Brown SJ et al., PMID: 19681860; Gruber R et al., PMID: 21514438; Mohiuddin MS et al., PMID: 24565632; Sandilands A et al., PMID: 17417636). This variant has been reported in the ClinVar database as a germline pathogenic variant by two submitters. This variant is only observed on 49/282666 alleles in the general population (gnomAD v.2.1.1), indicating it is not a common variant. This variant causes a frameshift by deleting a single nucleotide, leading to a premature termination codon; however, because this occurs in the last exon, this is not predicted to lead to nonsense mediated decay. There are at least three pathogenic variants that introduce a premature termination codon that occur downstream of this variant. Based on available information and the ACMG/AMP guidelines for variant interpretation (Richards S et al., PMID: 25741868), this variant is classified as pathogenic. -
