Digeorge syndrome hearing loss. Researchers havent yet isolated every single gene that contributes to the symptoms in DiGeorge syndrome. Congenital heart disease palate abnormalities immune system dysfunction including autoimmune disease low calcium hypocalcemia and other endocrine abnormalities such as thyroid problems and growth hormone deficiency gastrointestinal problems feeding difficulties kidney abnormalities hearing loss seizures skeletal. The age-dependent absence of DPOAEs in 22q112 deletion syndrome suggests cochlear damage underlying the high-frequency hearing loss.
DiGeorge syndrome is a condition present from birth that can cause a range of lifelong problems including heart defects and learning difficulties. Other conditions include kidney problems hearing loss and autoimmune disorders. The name of DiGeorge syndrome was applied to this group of features.
DiGeorge syndrome is associated with a range of problems including. Full text of GeneReview by section. Hearing loss can be sensorineural andor conductive.
The symptoms are caused by the lack of those genes. DiGeorge syndrome or 22q112 deletion syndrome is a syndrome caused by the deletion of a small segment of chromosome 22. The hearing loss is primarily of conductive origin with a predisposition to be bilateral with mixed HL typically have more severe loss.
68 with conductive hearing loss 14 with sensorineural hearing loss and 18 with mixed hearing loss. In the 1970s Robert Shprintzen PhD a speech pathologist described a group of patients with similar clinical features including cleft lip andor palate conotruncal heart defects absent or hypoplastic thymus and some of these patients also had hypocalcemia.
