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.740A>G (p.N247S) alteration is located in exon 1 (coding exon 1) of the ASPRV1 gene. This alteration results from a A to G substitution at nucleotide position 740, causing the asparagine (N) at amino acid position 247 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
