Genes affected

IVL (HGNC:6187): (involucrin) Involucrin, a component of the keratinocyte crosslinked envelope, is found in the cytoplasm and crosslinked to membrane proteins by transglutaminase. This gene is mapped to 1q21, among calpactin I light chain, trichohyalin, profillaggrin, loricrin, and calcyclin. [provided by RefSeq, Jul 2008]

The c.529G>C (p.E177Q) alteration is located in exon 2 (coding exon 1) of the IVL gene. This alteration results from a G to C substitution at nucleotide position 529, causing the glutamic acid (E) at amino acid position 177 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
