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.

The c.1001C>T (p.S334L) 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 1001, causing the serine (S) at amino acid position 334 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
