In 1998, an expert group defined the major (the classical 4C's: Choanal atresia, Coloboma, Characteristic ears and Cranial nerve anomalies) and minor criteria of CHARGE syndrome. Individuals with all four major characteristics or three major and three minor characteristics are highly likely to have CHARGE syndrome. Am J Med Genet Part A 146A:585–592. Cranial nerve VIII involvement manifests as sensorineural hearing loss. no previous family history) due to a de novo mutation in the CHD7 gene located on chromosome 8q12. Cranial nerve deficits are seen in 92% of patients and more than one nerve is involved in nearly 3 of 4 patients. The acronym features should never be used for diagnosis or even to describe the syndrome. VZV is latent in neurons of cranial nerve ganglia, dorsal root ganglia, and enteric and autonomic ganglia 2,36. radiological findings are exemplary for CHARGE syndrome and can assist diagnosis in a suspected case [21, 22]. CHARGE syndrome is a rare genetic disease that affects many areas of the body. CHARGE is characterized by various findings and conditions. Almost all mutations occurs de novo, but parent-to-child transmission has occasionally been reported [2]. [Google Scholar] In some cases, Duane syndrome is inherited from an affected parent. Multiple complex surgeries, along with the breathing problems or difficulty with anesthesia reported in CHARGE syndrome [Blake et al … CHARGE syndrome is a constellation of congenital malformations. Autosomal dominant diseases are expressed when only 1 copy of the dominant allele is inherited. The condition has a variable phenotypic expression. Moebius syndrome is caused by the absence or underdevelopment of the 6th and 7th cranial nerves, which control eye movement and facial expression. Cranial nerve deficits can affect cranial nerves III, IV, VI manifesting as ptosis, strabismus, esotropia, and/or amblyopia. Major features include ocular coloboma or microphthalmia, choanal atresia or stenosis, cranial nerve abnormalities, and characteristic auditory and/or auri- Pertinent problems are those with the glossopharyngeal and vagus nerves, which are responsible for innervating the pharynx and larynx and allowing swallowing to occur (Blake et al. The main chromosomes and genes involved in this syndrome are 8q12.1 (CHD7) and 7q21.11 (SEMA3E). Cranial nerve (CN) anomalies have been regarded as a major criterion for a clinical diagnosis of CHARGE syndrome for some time. It is a syndrome first described by Halle and Hittner et al in 1979. CHARGE syndrome is an autosomal dominant disorder characterized by multiple congenital malformations along with developmental and cognitive impairments. A comment on this article appears in "Facial palsy and cranial nerve abnormalities in CHARGE association. " CHARGE is the acronym that describes the following features: C oloboma, H eart defects, A tresia (choanal), R etardation (mental), G enital hypoplasia, and E ar abnormalities. Even in 1981, it was recognized that the acronym did not encompass all of the recognized features or even perhaps some of the most important features (e.g., cranial nerve anomalies). Individuals with SCS also have droopy eyelids (), … These nerves provide both motor control and sensation and include nerves involved in the senses of smell, taste, hearing, and vision, as well as movements of the eyes, face, tongue, palate, and swallowing. CHARGE is an acronym for coloboma of the eye (tissue in the eye is missing), heart anomalies, atresia of the choanae (back of the nasal passage is blocked), retardation of growth and development, genital anomalies, and ear anomalies. 60 to 80 percent of people have difficulty swallowing. Using an improved method of genome scan by comparative genomic hybridization (CGH), ... p = 0.022), and facial asymmetry, often caused by seventh cranial nerve abnormalities (36 of 56 in the mutation-positive group vs 13 of 39 in the mutation-negative group; p = 0.004). Some experts regard brittle diabetes as a subtype of type 1 diabetes while others believe it to be a complication of the disease. Cranial CT scan often reveals a hypoplastic cochlea (81%) with absent semicircular canals in most cases.   Read our diagnosis story and check out the FAQs here. Qualitative abnormalities such as changes in a density of lipoprotein composition may exist even when the usual clinical measurements of plasma lipids are normal (Dunn FL, 1992). In rare cases, it can be inherited in an autosomal dominant pattern. Disorders associated with CHARGE syndrome – Coloboma of the eye, Heart defects, Atresia of the nasal choanae, Retardation of growth, Genital and/or urinary abnormalities, and Ear abnormalities and deafness. 2009a). C—Coloboma and/or cranial nerves 2. CHARGE syndrome refers to a group of major and minor clinical features that include coloboma of the eye (hole in the lower part of the iris, retina and /or optic nerve that creates a void in the visual field), heart malformations, atresia of choanae (narrowing of the passage between the nasal cavity and the nasal pharynx), retarded growth and … Abnormalities of cranial nerve V … And there are several cranial nerves that are involved in these kids, which can cause a facial palsy, which can also interfere with breathing and swallowing as well as some other nerves. The next "C" is cranial nerve abnormalities. Other cranial nerves often affected control sucking, swallowing and smelling, which also lead to problems with their respective functioning. Choanal Atresia. Other cranial nerves often affected control sucking, swallowing and smelling, which also lead to problems with their respective functioning. At least 1 cranial nerve is involved in 75% of cases, and 2 or more cranial nerves are involved in 58% of cases. Major criteria include ocular coloboma, choanal atresia/stenosis, cranial nerve anomalies, and ear anomalies. Some affected individuals also have abnormally small or underdeveloped eyes ( microphthalmia ). 2003; 8:26B. Some abnormalities are more specific to CHARGE and so are called major diagnostic criteria (the four Cs): these include coloboma, choanal atresia, characteristic ear anomalies and cranial nerve dysfunction (the nerves that emerge directly from the brain). Infants with chest abnormalities may need to be evaluated for Poland's syndrome or Turner's syndrome. Breathing and swallowing may be affected . In this descriptive study the clinical and neurological issues related to CHARGE syndrome (C – coloboma, cranial nerves; H – heart defects; A – atresia of the choanae; R – retardation in growth, mental development, G – genital abnormalities, E – ear malformation / hearing loss) were assessed. Due to the range of symptoms for … However, there have been relatively few studies of the extent of this involvement.

CHARGE syndrome typically occurs spontaneously (i.e. Major Diagnostic Criteria (The 4 Cs): CHARGE syndrome, also known as CHARGE association, is a group of major and minor malformations that have been observed to occur together more frequently than expected by chance. Blake et al. Together these problems can affect health and the ability to speak and learn. Coloboma (cleft or failure to close the eyeball during fetal development) Cranial nerve abnormalities. Apart from clinical and ophthalmoscopic evaluation, imaging, especially magnetic resonance imaging (MRI), plays an important role in the complete evaluation of optic nerve and the entire visual pathway. We report a child with CHARGE syndrome and obstructive sleep apnea. It results from a lesion of the caudal pontine tegmentum and is most frequently defined as ipsilateral impairment of cranial nerves V, VI, VII, and VIII and contralateral sensory loss. The other 3 key diagnostic indicators are coloboma, choanal atresia, and characteristic ear anomalies. CHARGE syndrome can be inherited, ...
