Medium match CRANIOSYNOSTOSIS 7; CRS7

Craniosynostosis is a primary abnormality of skull growth involving premature fusion of the cranial sutures such that the growth velocity of the skull often cannot match that of the developing brain. This produces skull deformity and, in some cases, raises intracranial pressure, which must be treated promptly to avoid permanent neurodevelopmental disability (summary by Fitzpatrick, 2013).For a discussion of genetic heterogeneity of craniosynostosis, see CRS1 (OMIM ).

The Toriello-Carey syndrome is a multiple congenital anomaly disorder with variable systemic manifestations, most commonly including mental retardation, agenesis of the corpus callosum, postnatal growth delay, cardiac defects, usually septal defects, distal limb defects, and urogenital anomalies in affected males. Patients have facial dysmorphic features, micrognathia, including full cheeks, hypertelorism, flattened nasal bridge, anteverted nares, and short neck. Not all features are found in all patients and some patients may have additional features such as anal anomalies or hernias (review by Toriello et al., 2003).

17q12 microdeletion syndrome is a rare chromosomal anomaly syndrome resulting from the partial deletion of the long arm of chromosome 17 characterized by renal cystic disease, maturity onset diabetes of the young type 5, and neurodevelopmental disorders, such as cognitive impairment, developmental delay (particularly of speech), autistic traits and autism spectrum disorder. Müllerian aplasia in females, macrocephaly, mild facial dysmorphism (high forehead, deep set eyes and chubby cheeks) and transient hypercalcaemia have also been reported.

Additional more variable features include dysmorphic facial features, distal limb abnormalities, and mild heart defects (summary by Carter et al., 2011 and Mirzaa et al., 2011).

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.
