Crigler-Najjar syndrome type 1 (CNS1) is the most severe form of CNS (see this term), a hereditary disorder of hepatic bilirubin conjugation, characterized by severe neonatal unconjugated hyperbilirubinemia due to a complete absence of hepatic bilirubin glucuronosyltransferase (BGT).

Medium match GALACTOSE EPIMERASE DEFICIENCY

Epimerase-deficiency galactosemia was originally described as a benign condition in which GALE impairment is restricted to circulating red and white blood cells (Gitzelmann, 1972). Fibroblasts, liver, phytohemagglutinin-stimulated leukocyes, and Epstein Barr virus-transformed lymphoblasts from these patients all demonstrated normal or near-normal levels of GALE, leading to the designation 'peripheral' (or 'isolated') epimerase deficiency. A second form of epimerase deficiency became apparent in which a patient, despite normal GALT activity, presented with symptoms reminiscent of classic galactosemia and demonstrated severely impaired GALE activity in both red blood cells and fibroblasts (Holton et al., 1981). This form was designated 'generalized' epimerase deficiency. Openo et al. (2006) demonstrated that epimerase deficiency is in fact not a binary condition but is, rather, a continuum disorder.GALE encodes the third enzyme in the Leloir pathway of galactose metabolism. Galactosemia I is classic galactosemia (OMIM ), caused by deficiency of the second enzyme in the Leloir pathway, galactose-1-phosphate uridylyl-transferase (GALT ). Galactosemia II (OMIM ) is caused by deficiency of the first enzyme in the Leloir pathway, galactokinase (GALK ).

Non-acquired combined pituitary hormone deficiency-sensorineural hearing loss-spine abnormalities syndrome is a rare, genetic, non-acquired, combined pituitary hormone deficiency disorder characterized by panhypopituitarism (with or without ACTH deficiency) associated with spine abnormalities, including frequent rigid cervical spine and short neck with limited rotation, and variable degrees of sensorineural hearing loss. The anterior pituitary gland is usually abnormal (typically hypoplastic) and rarely a mild developmental delay or intellectual disability may be associated.

Stomatin-deficient cryohydrocytosis with neurologic defects is an autosomal dominant disorder characterized by delayed psychomotor development, seizures, cataracts, and pseudohyperkalemia resulting from defects in the red blood cell membrane. The disorder combines the neurologic features of Glut1 deficiency syndrome-1 (GLUT1DS1 ), resulting from impaired glucose transport at the blood-brain barrier, and hemolytic anemia/pseudohyperkalemia with stomatocytosis, resulting from a cation leak in erythrocytes (summary by Bawazir et al., 2012).For a discussion of clinical and genetic heterogeneity of red cell stomatocyte disorders, see {194380}.

Medium match PROLIDASE DEFICIENCY

Prolidase deficiency is a rare autosomal recessive multisystem disorder associated with massive imidodipeptiduria and lack of or reduced prolidase activity in erythrocytes, leukocytes, or cultured fibroblasts. The disorder is clinically heterogeneous and severity varies widely. Features include chronic, slowly healing ulcerations, mainly on the legs and feet. The ulcers are often preceded by other dermatologic manifestations that may occur anywhere and include erythematous papular eruptions, telangiectasias with pruritus and photosensitivity, impetigo-like eruptions, pruritic eczematous lesions, and necrotic papules. Mild to severe mental retardation is often a feature, and recurrent respiratory tract infections, sometimes fatal, are common. Facial dysmorphism may include low hairline and hirsutism, saddle nose, ocular hypertelorism, micrognathia, a high-arched palate, mandibular protrusion, and exophthalmos. Clinical manifestations are usually detectable after birth or in early childhood, but late-onset cases have been reported (summary by Lupi et al., 2008).

Medium match PEROXISOME BIOGENESIS DISORDER 1B; PBD1B

Peroxisome biogenesis disorder-1B (PBD1B) is characterized by the overlapping phenotypes of neonatal adrenoleukodystrophy (NALD) and infantile Refsum disease (IRD), which represent the milder manifestations of the Zellweger syndrome spectrum (ZSS) of peroxisome biogenesis disorders (PBDs). Initial presentation and natural history varies, with many children presenting as newborns, whereas others do not come to attention until later. Most affected children have hypotonia, but unlike Zellweger syndrome (see PBD1A, {214100}) there is a degree of psychomotor development, and some patients achieve head control, sit unsupported, and may even walk independently. Many can communicate, and although language is rare, there have been children who have near normal language for age. Craniofacial anomalies are similar to but less pronounced than in Zellweger syndrome. In some individuals a leukodystrophy develops, with degeneration of myelin, loss of previously acquired skills, and development of spasticity; this may stabilize, or progress and be fatal. In PBD1B, the most common manifestations that are less apparent in ZS are sensorineural hearing loss and retinitis pigmentosa (summary by Steinberg et al., 2006). While Zellweger syndrome usually results in death in the first year of life, children with the NALD presentation may reach their teens, and those with the IRD presentation may reach adulthood (summary by Waterham and Ebberink, 2012).Individuals with mutations in the PEX1 gene have cells of complementation group 1 (CG1, equivalent to CGE). For information on the history of PBD complementation groups, see {214100}. Genetic Heterogeneity of Peroxisome Biogenesis Disorder NALD/IRDThe phenotypic spectrum of NALD/IRD peroxisome biogenesis disorders can be caused by mutation in members of the peroxin (PEX) gene family. The PEX genes encode proteins essential for the assembly of functional peroxisomes (summary by Distel et al., 1996). PBD1B is caused by mutation in the PEX1 gene on chromosome 7q21; PBD2B (OMIM ) is caused by mutation in the PEX5 gene (OMIM ) on chromosome 12p13.3; PBD3B (OMIM ) is caused by mutation in the PEX12 gene (OMIM ) on chromosome 17; PBD4B (OMIM ) is caused by mutation in the PEX6 gene (OMIM ) on chromosome 6p21.1; PBD5B (OMIM ) is caused by mutation in the PEX2 gene (OMIM ) on chromosome 8q21.1; PBD6B (OMIM ) is caused by mutation in the PEX10 gene (OMIM ) on chromosome 1p36.32; PBD7B (OMIM )is caused by mutation in the PEX26 gene (OMIM ) on chromosome 22q11.21; PBD8B (OMIM ) is caused by mutation in the PEX16 gene (OMIM ) on chromosome 11p11; PDB10B (OMIM ) is caused by mutation in the PEX3 gene (OMIM ) on chromosome 6q24; and PBD11B (OMIM ) is caused by mutation in the PEX13 gene (OMIM ) on chromosome 2p15.See PBD1A (OMIM ) for a phenotypic description and a discussion of genetic heterogeneity of Zellweger syndrome, which is also caused by mutation in peroxin genes. The rhizomelic chondrodysplasia subtype of PBD (RCDP1, PBD9; {215100}), and a mild PBD without rhizomelia (PBD9B ), are caused by mutation in the PEX7 gene (OMIM ) on chromosome 6q23.
