Disease ID | Source | Name | Description |
612938 | OMIM | Growth retardation, developmental delay, and facial dysmorphism (GDFD) | A severe polymalformation syndrome characterized by postnatal growth retardation, microcephaly, severe psychomotor delay, functional brain deficits and characteristic facial dysmorphism. In some patients, structural brain malformations, cardiac defects, genital anomalies, and cleft palate are observed. Early death occurs by the age of 3 years. The disease is caused by variants affecting the gene represented in this entry. |
601665 | OMIM | Obesity (OBESITY) | A condition characterized by an increase of body weight beyond the limitation of skeletal and physical requirements, as the result of excessive accumulation of body fat. Disease susceptibility is associated with variants affecting the gene represented in this entry. It is unclear whether variations associated with obesity directly affect FTO function or alter the expression of adjacent genes such as IRX3, rather than FTO itself (PubMed:24646999, PubMed:26287746). A pathogenic intronic FTO variation (rs1421085) disrupts an evolutionarily conserved motif for ARID5B binding (PubMed:26287746). Loss of ARID5B binding results in overexpression of two genes distal to FTO, IRX3 and IRX5. IRX3 and IRX5 overexpression shifts pre-adipocytes differentiation from brown to white fat cells, resulting in increased lipid storage and loss of mitochondrial thermogenesis (PubMed:26287746). |
