Disease Profile

Autosomal recessive intellectual disability 58

Prevalence
Prevalence estimates on Rare Medical Network websites are calculated based on data available from numerous sources, including US and European government statistics, the NIH, Orphanet, and published epidemiologic studies. Rare disease population data is recognized to be highly variable, and based on a wide variety of source data and methodologies, so the prevalence data on this site should be assumed to be estimated and cannot be considered to be absolutely correct.

Inheritance

Autosomal dominant A pathogenic variant in only one gene copy in each cell is sufficient to cause an autosomal dominant disease.

no.svg

Autosomal recessive Pathogenic variants in both copies of each gene of the chromosome are needed to cause an autosomal recessive disease and observe the mutant phenotype.

no.svg

X-linked
dominant X-linked dominant inheritance, sometimes referred to as X-linked dominance, is a mode of genetic inheritance by which a dominant gene is carried on the X chromosome.

no.svg

X-linked
recessive Pathogenic variants in both copies of a gene on the X chromosome cause an X-linked recessive disorder.

no.svg

Mitochondrial or multigenic Mitochondrial genetic disorders can be caused by changes (mutations) in either the mitochondrial DNA or nuclear DNA that lead to dysfunction of the mitochondria and inadequate production of energy.

no.svg

Multigenic or multifactor Inheritance involving many factors, of which at least one is genetic but none is of overwhelming importance, as in the causation of a disease by multiple genetic and environmental factors.

Summary

Autosomal recessive intellectual disability 58 is a very rare genetic condition characterized by intellectual disability without identified malformations in other organs (non-syndromic) of the body. To date, there are only eight cases reported in the medical literature. Symptoms severity varied in the reported cases, with mild or severe intellectual disability.[1] In one family with two affected brothers, one was not able to walk at age 9 due to progressive spasticity (stiffness or tightness of the muscles with too strong or persistent reflexes) and difficulty talking, and the other never walked or talked. Both brothers had behavioral problems, such as aggressiveness, impulsivity, and self-injury.[2] It is caused by mutations in the ELP2 gene. In the reported cases inheritance seems to be autosomal recessive.[1] There is no report of specific treatment.

Symptoms

This table lists symptoms that people with this disease may have. For most diseases, symptoms will vary from person to person. People with the same disease may not have all the symptoms listed. This information comes from a database called the Human Phenotype Ontology (HPO) . The HPO collects information on symptoms that have been described in medical resources. The HPO is updated regularly. Use the HPO ID to access more in-depth information about a symptom.
