GRACILE syndrome is an inherited lethal mitochondrial disorder characterized by fetal growth restriction (GR), aminoaciduria (A), cholestasis (C), iron overload (I), lactacidosis (L), and early death (E).

Immunodeficiency-47 is an X-linked recessive complex immunodeficiency syndrome characterized by recurrent bacterial infections, hypogammaglobulinemia, liver dysfunction, and defective glycosylation of serum proteins. Some patients may also have neurologic abnormalities (summary by Jansen et al., 2016).

COXPD34 is an autosomal recessive disorder resulting from a defect in mitochondrial function. The phenotype is variable, but may include congenital sensorineural deafness, increased serum lactate, and hepatic and renal dysfunction. Neurologic function is relatively preserved (summary by Menezes et al., 2015).For a discussion of genetic heterogeneity of combined oxidative phosphorylation deficiency, see COXPD1 (OMIM ).

Acute infantile liver failure-multisystemic involvement syndrome is a rare, genetic, parenchymal hepatic disease characterized by acute liver failure, that occurs in the first year of life, which manifests with failure to thrive, hypotonia, moderate global developmental delay, seizures, abnormal liver function tests, microcytic anemia and elevated serum lactate. Other associated features include hepatosteatosis and fibrosis, abnormal brain morphology, and renal tubulopathy. Minor illness exacerbates deterioration of liver failure.

GRIDHH is an autosomal recessive multisystem disorder characterized by intellectual disability, poor overall growth, hypotonia, and variable liver dysfunction. Additional features, such as seizures and hearing loss, may also be present (summary by Kopajtich et al., 2016).

BBS16 is an autosomal recessive ciliopathy characterized by retinal degeneration, obesity, renal disease, and cognitive impairment. Although polydactyly is considered a primary feature of BBS overall, it has not been reported in any BBS16 patient (Billingsley et al., 2012).For a general phenotypic description and a discussion of genetic heterogeneity of Bardet-Biedl syndrome, see BBS1 (OMIM ).

Hypermethioninemia encephalopathy due to adenosine kinase deficiency is a rare inborn error of metabolism disorder characterized by persistent hypermethioninemia with increased levels of S-adenosylmethionine and S-adenosylhomocysteine which manifests with encephalopathy, severe global developmental delay, mild to severe liver dysfunction, hypotonia and facial dysmorphism (most significant is frontal bossing, macrocephaly, hypertelorism and depressed nasal bridge). Epileptic seizures, hypoglycemia and/or cardiac defects (pulmonary stenosis, atrial and/or ventricular septal defect, coarctation of the aorta) may be associated. Clinical picture may range from neurological symptoms only to multi-organ involvement.

Neutral lipid storage disease with myopathy is an autosomal recessive muscle disorder characterized by adult onset of slowly progressive proximal muscle weakness affecting the upper and lower limbs and associated with increased serum creatine kinase; distal muscle weakness may also occur. About half of patients develop cardiomyopathy later in the disease course. Other variable features include diabetes mellitus, hepatic steatosis, hypertriglyceridemia, and possibly sensorineural hearing loss. Leukocytes and muscle cells show cytoplasmic accumulation of triglycerides (summary by Reilich et al., 2011).Neutral lipid storage disease with myopathy belongs to a group of disorders termed neutral lipid storage disorders (NLSDs). These disorders are characterized by the presence of triglyceride-containing cytoplasmic droplets in leukocytes and in other tissues, including bone marrow, skin, and muscle. Chanarin-Dorfman syndrome (CDS ) is defined as NLSD with ichthyosis (NLSDI). Patients with NLSDM present with myopathy but without ichthyosis (summary by Fischer et al., 2007).
