Joubert syndrome-14 is an autosomal recessive developmental disorder characterized by severe mental retardation, hypoplasia of the cerebellar vermis and molar tooth sign (MTS) on brain imaging, hypotonia, abnormal breathing pattern in infancy, and dysmorphic facial features. Additional findings can include renal cysts, abnormal eye movements, and postaxial polydactyly (summary by Boycott et al., 2007 and Huang et al., 2011).For a phenotypic description and a discussion of genetic heterogeneity of Joubert syndrome, see {213300}.

Progeroid and marfanoid aspect-lipodystrophy syndrome is a rare systemic disease characterized by a neonatal progeroid appearance (not associated with other manifestations of premature aging) associated with facial dysmorphism (e.g. macrocephaly or arrested hydrocephaly, proptosis, downslanting palpebral fissures, retrognathia), generalized, extreme, congenital lack of subcutaneous fat tissue (except in the breast and iliac region) and incomplete signs of Marfan syndrome (mainly severe myopia, joint hyperextensibility and arachnodactyly). Metabolic disturbances are not associated.

Medium match MITOCHONDRIAL COMPLEX V (ATP SYNTHASE) DEFICIENCY, NUCLEAR TYPE 1; MC5DN1

A distinct group of inborn defects of complex V (ATP synthase) is represented by the enzyme deficiency due to nuclear genome mutations characterized by a selective inhibition of ATP synthase biogenesis. Biochemically, the patients show a generalized decrease in the content of ATP synthase complex which is less than 30% of normal. Most cases present with neonatal-onset hypotonia, lactic acidosis, hyperammonemia, hypertrophic cardiomyopathy, and 3-methylglutaconic aciduria. Many patients die within a few months or years (summary by Mayr et al., 2010). Genetic Heterogeneity of Mitochondrial Complex V DeficiencyOther nuclear types of mitochondrial complex V deficiency include MC5DN2 (OMIM ), caused by mutation in the TMEM70 gene (OMIM ) on chromosome 8q21; MC5DN3 (OMIM ), caused by mutation in the ATP5E gene (ATP5F1E ) on chromosome 20q13; MC5DN4 (OMIM ), caused by mutation in the ATP5A1 gene (ATP5FA1 ) on chromosome 18q; and MC5DN5 (OMIM ), caused by mutation in the ATP5D gene (ATP5F1D ) on chromosome 19p13.Mutations in the mitochondrial-encoded MTATP6 (OMIM ) and MTATP8 (OMIM ) genes can also cause mitochondrial complex V deficiency (see, e.g., {551500} and {500003}).

Potocki-Shaffer syndrome is characterized by multiple exostoses, parietal foramina, enlargement of the anterior fontanelle and occasionally intellectual deficit and mild cranio-facial anomalies. To date, 23 individuals from 14 families have been reported. The syndrome is caused by contiguous gene deletions on the short arm of chromosome 11 (11p11.2).

Medium match CUTIS GYRATA-ACANTHOSIS NIGRICANS-CRANIOSYNOSTOSIS SYNDROME

Cutis gyrata-acanthosis nigricans-craniosynostosis syndrome, also known as Beare-Stevenson syndrome (BSS), is a severe form of syndromic craniosynostosis, characterized by a variable degree of craniosynostosis, with cloverleaf skull reported in over 50% of cases, cutis gyrata, corduroy-like linear striations in the skin, acanthosis nigricans, skin tags, and choanal stenosis or atresia). Additional features include facial features similar to Crouzon disease, ear defects (conductive hearing loss, posteriorly angulated ears, stenotic auditory canals, preauricular furrows, and narrow ear canals), hirsutism, a prominent umbilical stump, and genitorurinary anomalies (anteriorly placed anus, hypoplasic labia, hypospadias). BSS is associated with a poor outcome as patients present an elevated risk for sudden death in their first year of life. Significant developmental delay and intellectual disability are observed in most patients who survive infancy.
