Immunodeficiency, centromeric instability and facial dysmorphism (ICF syndrome) is a genetically heterogeneous autosomal recessive disorder. It is characterized by recurrent and often fatal respiratory and gastrointestinal infections as a consequence of hypogammaglobulinemia in the presence of B cells. Nearly all patients also present with distinct facial anomalies. Centromeric instability is the cytogenetic hallmark of ICF syndrome. Mutations in the DNA methyltransferase 3B (DNMT3B) gene account for about 50% of ICF cases, while about 30% of cases have mutations in the ZBTB24 gene. Recently, it has been reported that mutations in CDCA7 and HELLS cause ICF syndrome.

Title
Mutations in CDCA7 and HELLS cause immunodeficiency-centromeric instability-facial anomalies syndrome.
Facioscapulohumeral muscular dystrophy (FSHD) is a usually autosomal dominant inherited form of muscular dystrophy. At disease onset, typically in the second decade of life, FSHD is characterized by initially restricted weakness of shoulder and facial muscles. With progression, the lower extremities, both distal and proximal, become involved. FSHD is caused by a reduction in the copy number of the D4Z4 macrosatellite repeat. However, the reduction of D4Z4 copy number is not sufficient by itself to cause FSHD. A number of epigenetic events appear to affect the severity of the disease, its rate of progression, and the distribution of muscle weakness.
