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]

Feb 13, 2024

The c.331A>G (p.N111D) alteration is located in exon 6 (coding exon 5) of the SCEL gene. This alteration results from a A to G substitution at nucleotide position 331, causing the asparagine (N) at amino acid position 111 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
