Summaries for Immunodeficiency-Centromeric Instability-Facial Anomalies...

OMIM : 58 Immunodeficiency, centromeric instability, and facial dysmorphism (ICF) syndrome is a rare autosomal recessive disorder characterized by facial dysmorphism, immunoglobulin deficiency resulting in recurrent infections, and mental retardation. Laboratory studies of patient cells show hypomethylation of satellite regions of chromosomes 1, 9, and 16, as well as pericentromeric chromosomal instability in response to phytohemagglutinin stimulation (summary by de Greef et al., 2011). For a discussion of genetic heterogeneity of immunodeficiency-centromeric instability-facial anomalies syndrome, see ICF1 (242860). (614069)

MalaCards based summary : Immunodeficiency-Centromeric Instability-Facial Anomalies Syndrome 2, also known as icf2, is related to immunodeficiency-centromeric instability-facial anomalies syndrome and combined t cell and b cell immunodeficiency. An important gene associated with Immunodeficiency-Centromeric Instability-Facial Anomalies Syndrome 2 is ZBTB24 (Zinc Finger And BTB Domain Containing 24). Affiliated tissues include b cells, t cells and testes, and related phenotypes are hypertelorism and low-set ears

Disease Ontology : 12 An immunodeficiency-centromeric instability-facial anomalies syndrome characterized by autosomal recessive inheritance, facial dysmorphism, immunoglobulin deficiency resulting in recurrent infections, and mental retardation that has material basis in homozygous or compound heterozygous mutation in the ZBTB24 gene on chromosome 6q21.

UniProtKB/Swiss-Prot : 76 Immunodeficiency-centromeric instability-facial anomalies syndrome 2: A rare disorder characterized by a variable immunodeficiency resulting in recurrent infections, facial anomalies, and branching of chromosomes 1, 9, and 16. Other variable symptoms include growth retardation, failure to thrive, and psychomotor retardation. Laboratory studies show limited hypomethylation of DNA in a small fraction of the genome in some, but not all, patients.
