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)

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -18 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.84).
BP6
Variant 1-152302796-C-T is Benign according to our data. Variant chr1-152302796-C-T is described in ClinVar as [Likely_benign]. Clinvar id is 1211343.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BP7
Synonymous conserved (PhyloP=-1.76 with no splicing effect.
BS1
Variant frequency is greater than expected in population eas. gnomad4 allele frequency = 0.00237 (361/152268) while in subpopulation EAS AF= 0.0268 (139/5186). AF 95% confidence interval is 0.0232. There are 7 homozygotes in gnomad4. There are 182 alleles in male gnomad4 subpopulation. Median coverage is 31. This position pass quality control queck.
BS2
High Homozygotes in GnomAd4 at 7 SD geneVariant has number of homozygotes lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
