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 GeneticsMar 18, 2024The c.334G>A (p.V112I) alteration is located in exon 1 (coding exon 1) of the ASPRV1 gene. This alteration results from a G to A substitution at nucleotide position 334, causing the valine (V) at amino acid position 112 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
