Genes affected

ZNF300 (HGNC:13091): (zinc finger protein 300) The protein encoded by this gene is a C2H2-type zinc finger DNA binding protein and likely transcriptional regulator. The function of this protein is not yet known. Three transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Mar 2010]

ZNF300 links:

IRGM (HGNC:29597): (immunity related GTPase M) This gene encodes a member of the p47 immunity-related GTPase family. The encoded protein may play a role in the innate immune response by regulating autophagy formation in response to intracellular pathogens. Polymorphisms that affect the normal expression of this gene are associated with a susceptibility to Crohn's disease and tuberculosis. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Oct 2016]

The c.808C>A (p.Q270K) alteration is located in exon 7 (coding exon 5) of the ZNF300 gene. This alteration results from a C to A substitution at nucleotide position 808, causing the glutamine (Q) at amino acid position 270 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
