Entire Body System

  • Disability

    Micro syndrome also known as WARBM, and Warburg–Sjo–Fledelius syndrome, is a rare autosomal recessive genetic disorder characterized by microcephaly, microcornea, congenital cataract, intellectual or developmental disability, optic atrophy, and hypogenitalism [dbpedia.org]

    From Wikidata Jump to navigation Jump to search autosomal recessive disease characterized by severe intellectual disability, microcephaly, congenital cataract, microcornea, microphthalmia, agenesis or hypoplasia of the corpus callosum and hypogenitalism [wikidata.org]

    The cardinal features are microcephaly, microphthalmia, congenital cataract and intellectual disability. [ncbi.nlm.nih.gov]

    Intellectual or developmental disabilities can seriously affect a patient in the way they think and move. [wikivisually.com]

  • Infertility

    The findings have been published in The American Journal of Human Genetics, in a paper titled “Loss-of-Function Mutations in TBC1D20 Cause Cataracts and Male Infertility in blind sterile Mice and Warburg Micro Syndrome in Humans.” [digitaljournal.com]

  • Seizure

    In particular, 6 out of 13 patients had epilepsy, 3 with generalized tonic clonic seizures and the other 3 with myoclonic seizures. In two siblings reported by [ 2 ], the age at onset of myoclonic seizures was respectively 5 and 3 years. [omicsonline.org]

Workup

Clinical Testing and Workup A thorough eye (ophthalmological) examination is necessary in infants suspected of Warburg Micro syndrome. Such an exam can reveal characteristic changes in the eyes. [rarediseases.org]

Treatment

PMID 26063829. ^ "Are There Treatments for Warburg Micro." https://www.warburgmicro.org/treatment/ 27 Mar. 2022. [en.wikipedia.org]

Treatment Treatment Options: No effective treatment is available. Vision remains subnormal even after cataracts are removed. Nutrition may be improved with placement of a gastrostomy tube. [disorders.eyes.arizona.edu]

Management and treatment There is no specific treatment for Micro syndrome and the management is symptomatic. The conventional approach used for congenital cataract should be recommended. Last updated: 1/16/2006 [rarediseases.info.nih.gov]

[…] differs from COFS and CS in that patients have less prenatal and postnatal growth deficiency, cortical dysplasia rather than progressive brain atrophy, preservation of hearing, deficient visual perception despite early cataract removal, and a better prognosis [doi.org]

Etiology

Etiology Mutations in RAB3GAP, a gene showing linkage to a region of homozygosity at 2q21.3, have been identified in some families. [rarediseases.info.nih.gov]

Symptomatic treatment is not always recommended, and in fact, it may be dangerous, because it may mask the presence of an underlying etiology which will then be forgotten or treated with great delay. [en.wikipedia.org]
