Low match ONDINE SYNDROME

Congenital central hypoventilation syndrome (CCHS) is a rare disease due to a severely impaired central autonomic control of breathing and dysfunction of the autonomous nervous system. The incidence is estimated to be at 1 of 200 000 livebirths. A heterozygous mutation of PHOX-2B gene is found in 90% of the patients. Association with a Hirschsprung's disease is observed in 16% of the cases. Despite a high mortality rate and a lifelong dependence to mechanical ventilation, the long-term outcome of CCHS should be ultimately improved by multidisciplinary and coordinated follow-up of the patients.

Low match RUBINSTEIN-TAYBI SYNDROME 1; RSTS1

Rubinstein-Taybi syndrome is a multiple congenital anomaly syndrome characterized by mental retardation, postnatal growth deficiency, microcephaly, broad thumbs and halluces, and dysmorphic facial features. The facial appearance is striking, with highly arched eyebrows, long eyelashes, downslanting palpebral fissures, broad nasal bridge, beaked nose with the nasal septum, highly arched palate, mild micrognathia, and characteristic grimacing or abnormal smile. Affected individuals also have an increased risk of tumor formation (Rubinstein and Taybi, 1963; review by Hennekam, 2006).Floating-Harbor syndrome (OMIM ), which shows phenotypic overlap with Rubinstein-Taybi syndrome, is caused by mutation in the SRCAP gene (OMIM ), a coactivator for CREBBP. Genetic Heterogeneity of Rubinstein-Taybi SyndromeRubinstein-Taybi syndrome-1 (RSTS1) constitutes about 50 to 70% of patients with the disorder. Rubinstein-Taybi syndrome-2 (RSTS2 ) comprises about 3% of patients and is primarily due to de novo heterozygous mutation in the EP300 gene (OMIM ) on chromosome 22q13 (Bartsch et al., 2010).See also chromosome 16p13.3 deletion syndrome (OMIM ), a severe form of Rubinstein-Taybi syndrome resulting from a contiguous gene deletion involving the CREBBP gene as well as other neighboring genes.

Low match PAPILLOMA OF CHOROID PLEXUS; CPP

Choroid plexus tumors are of neuroectodermal origin and range from benign choroid plexus papillomas (CPPs) to malignant choroid carcinomas (CPCs). These rare tumors generally occur in childhood, but have also been reported in adults. Patients typically present with signs and symptoms of increased intracranial pressure including headache, hydrocephalus, papilledema, nausea, vomiting, cranial nerve deficits, gait impairment, and seizures (summary by Safaee et al., 2013).

Low match CONGENITAL ALPHA2-ANTIPLASMIN DEFICIENCY

Congenital alpha2 antiplasmin deficiency is a rare hemorrhagic disorder (see this term)caused by congenital deficiency of alpha2 antiplasmin, leading to dysregulated fibrinolysis and is characterized by a hemorrhagic tendency presenting from childhood with prolonged bleeding and ecchymoses following minor trauma and spontaneous bleeding episodes (often in unusual locations like diaphysis of long bones). Congenital alpha2 antiplasmin deficiency is inherited in an autosomal recessive manner.

Low match MULTIPLE ACYL-COA DEHYDROGENASE DEFICIENCY; MADD

Glutaric aciduria II (GA2) is an autosomal recessively inherited disorder of fatty acid, amino acid, and choline metabolism. It differs from GA I (GA1 ) in that multiple acyl-CoA dehydrogenase deficiencies result in large excretion not only of glutaric acid, but also of lactic, ethylmalonic, butyric, isobutyric, 2-methyl-butyric, and isovaleric acids. GA II results from deficiency of any 1 of 3 molecules: the alpha (ETFA) and beta (ETFB) subunits of electron transfer flavoprotein, and electron transfer flavoprotein dehydrogenase (ETFDH). The clinical picture of GA II due to the different defects appears to be indistinguishable; each defect can lead to a range of mild or severe cases, depending presumably on the location and nature of the intragenic lesion, i.e., mutation, in each case (Goodman, 1993; Olsen et al., 2003).The heterogeneous clinical features of patients with MADD fall into 3 classes: a neonatal-onset form with congenital anomalies (type I), a neonatal-onset form without congenital anomalies (type II), and a late-onset form (type III). The neonatal-onset forms are usually fatal and are characterized by severe nonketotic hypoglycemia, metabolic acidosis, multisystem involvement, and excretion of large amounts of fatty acid- and amino acid-derived metabolites. Symptoms and age at presentation of late-onset MADD are highly variable and characterized by recurrent episodes of lethargy, vomiting, hypoglycemia, metabolic acidosis, and hepatomegaly often preceded by metabolic stress. Muscle involvement in the form of pain, weakness, and lipid storage myopathy also occurs. The organic aciduria in patients with the late-onset form of MADD is often intermittent and only evident during periods of illness or catabolic stress (summary by Frerman and Goodman, 2001).Importantly, riboflavin treatment has been shown to ameliorate the symptoms and metabolic profiles in many MADD patients, particularly those with type III, the late-onset and mildest form (Liang et al., 2009).
