Genes affected
ASPRV1 (HGNC:26321): (aspartic peptidase retroviral like 1) Filaggrin is a structural protein that is crucial for in the development and maintenance of the skin barrier. This gene encodes a retroviral-like protease involved in profilaggrin-to-filaggrin processing. Expression is found primarily in the epidermis and inner root sheath of hair follicles.

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 21, 2022The c.457C>T (p.L153F) alteration is located in exon 1 (coding exon 1) of the ASPRV1 gene. This alteration results from a C to T substitution at nucleotide position 457, causing the leucine (L) at amino acid position 153 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
