Genes affected

KRT24 (HGNC:18527): (keratin 24) This gene encodes a member of the type I (acidic) keratin family, which belongs to the superfamily of intermediate filament (IF) proteins. Keratins are heteropolymeric structural proteins which form the intermediate filament. These filaments, along with actin microfilaments and microtubules, compose the cytoskeleton of epithelial cells. The type I keratin genes are clustered in a region of chromosome 17q12-q21. [provided by RefSeq, Jun 2009]

The c.1447T>C (p.S483P) alteration is located in exon 7 (coding exon 7) of the KRT24 gene. This alteration results from a T to C substitution at nucleotide position 1447, causing the serine (S) at amino acid position 483 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
