Bartsocas-Papas syndrome is a rare, inherited, popliteal pterygium syndrome characterized by severe popliteal webbing, microcephaly, a typical face with short palpebral fissures, ankyloblepharon, hypoplastic nose, filiform bands between the jaws and facial clefts, oligosyndactyly, genital abnormalities, and additional ectodermal anomalies (i.e. absent hair, eyebrows, lashes, nails). It is often fatal in the neonatal period, but patients living until childhood have been reported. |

A rare systemic disease characterized by progressive hyalinosis involving capillaries, arterioles and small veins of the digestive tract, kidneys, and retina, associated with idiopathic cerebral calcifications, manifesting with severe diarrhea (with rectal bleeding and malabsorption), nephropathy (with renal failure and systemic hypertension), chorioretinal scarring, and subarachnoid hemorrhage. Poikiloderma and premature graying of the hair may be additionally observed. |

A rare, multisystemic inherited metabolic disease characterized clinically, by a variable spectrum of severity, primarily comprised of psychomotor delay, myopathy and liver dysfunction. Most patients present in infancy, but the onset can be already in utero or in adult age. Hypermethioninemia is frequent, but often absent in infancy. Creatine kinase is elevated in most patients. |

A rare form of disorder of protein N-glycosylation characterised by facial dysmorphism (large, posteriorly rotated ears with prominent antihelices, convex nasal ridge, open mouth, large and crowded teeth), stereotypic hand movements, seizures, and varying degrees of developmental delay. A bleeding tendency is also observed and this results from diminished platelet aggregation. The disease is caused by loss-of-function mutations in the gene MGAT2 (14q21). |
