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]
FLG-AS1 (HGNC:27913): (cervical cancer associated DHX9 suppressive transcript)

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 11, 2024The c.11872T>A (p.Y3958N) alteration is located in exon 3 (coding exon 2) of the FLG gene. This alteration results from a T to A substitution at nucleotide position 11872, causing the tyrosine (Y) at amino acid position 3958 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
