Genes affected
SCEL (HGNC:10573): (sciellin) The protein encoded by this gene is a precursor to the cornified envelope of terminally differentiated keratinocytes. This protein localizes to the periphery of cells and may function in the assembly or regulation of proteins in the cornified envelope. Transcript variants encoding different isoforms exist. A transcript variant utilizing an alternative polyA signal has been described in the literature, but its full-length nature has not been determined. [provided by RefSeq, Jul 2008]
SCEL-AS1 (HGNC:39895): (SCEL antisense RNA 1)

The c.881T>C (p.I294T) alteration is located in exon 15 (coding exon 14) of the SCEL gene. This alteration results from a T to C substitution at nucleotide position 881, causing the isoleucine (I) at amino acid position 294 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
