Description : Immunodeficiency, centromeric instability, and facial dysmorphism (ICF) syndrome is
a rare autosomal recessive disease characterized by facial dysmorphism, immunoglobulin
deficiency, and branching of chromosomes 1, 9, and 16 after phytohemagglutinin (PHA)
stimulation of lymphocytes. Hypomethylation of DNA of a small fraction of the genome
is an unusual feature of ICF patients that is explained by mutations in the DNMT3B
gene in some, but not all, ICF patients (Hagleitner et al., 2008). - Genetic Heterogeneity
of Immunodeficiency-Centromeric Instability-Facial Anomalies Syndrome ICF2 (614069)
is caused by mutation in the ZBTB24 gene (614064) on chromosome 6q21.;
Inheritance : Autosomal recessive;
Molecular basis : Caused by mutation in the DNA methyl-transferase 3B gene (DNMT3B, 602900.0001);
Laboratory abnormalities : Increased IgM; Reduced IgA;
Prefixed ID : #242860;
