Genes affected

IFNK (HGNC:21714): (interferon kappa) This gene encodes a member of the type I interferon family. Type I interferons are a group of related glycoproteins that play an important role in host defenses against viral infections. This protein is expressed in keratinocytes and the gene is found on chromosome 9, adjacent to the type I interferon cluster. [provided by RefSeq, Jul 2008]

IFNK links:

MOB3B (HGNC:23825): (MOB kinase activator 3B) The protein encoded by this gene shares similarity with the yeast Mob1 protein. Yeast Mob1 binds Mps1p, a protein kinase essential for spindle pole body duplication and mitotic checkpoint regulation. This gene is located on the opposite strand as the interferon kappa precursor (IFNK) gene. [provided by RefSeq, Jul 2008]

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.14C>G (p.P5R) alteration is located in exon 1 (coding exon 1) of the IFNK gene. This alteration results from a C to G substitution at nucleotide position 14, causing the proline (P) at amino acid position 5 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
