Genes affected

PIBF1 (HGNC:23352): (progesterone immunomodulatory binding factor 1) This gene encodes a protein that is induced by the steroid hormone progesterone and plays a role in the maintenance of pregnancy. The encoded protein regulates multiple facets of the immune system to promote normal pregnancy including cytokine synthesis, natural killer (NK) cell activity, and arachidonic acid metabolism. Low serum levels of this protein have been associated with spontaneous pre-term labor in humans. This protein may promote the proliferation, migration and invasion of glioma.

Significance:Pathogenic

Review Status:no assertion criteria provided

Collection Method:clinical testing

The PIBF1 c.1910A>C variant is predicted to result in the amino acid substitution p.Asp637Ala. This variant was reported in the homozygous state in two brothers with Joubert syndrome lacking other known pathogenic variants, and was found to decrease normal protein function (Wheway et al. 2015. PubMed ID: 26167768). At PreventionGenetics, this variant was detected in the homozygous state in an individual referred for Joubert syndrome testing. This variant is reported in 0.0018% of alleles in individuals of European (Non-Finnish) descent in gnomAD. This variant is interpreted as pathogenic. -
