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]

CCDST (HGNC:55988): (cervical cancer associated DHX9 suppressive transcript)

ACMG classification

Our verdict: Pathogenic. The variant received 10 ACMG points.

• PVS1: Loss of function variant, product does not undergo nonsense mediated mRNA decay. Variant is located in the 3'-most exon, not predicted to undergo nonsense mediated mRNA decay. There are 143 pathogenic variants in the truncated region.
• PP5: Variant 1-152309716-C-A is Pathogenic according to our data. Variant chr1-152309716-C-A is described in ClinVar as Pathogenic. ClinVar VariationId is 522879.Status of the report is criteria_provided_single_submitter, 1 stars.
