A rare congenital disorder of bone resorption characterised by generalised skeletal densification. Bone marrow failure, fractures and visual impairment are the classical features of the disease, which begins in early infancy or in fetal life. It results from the failure of osteoclasts to resorb immature bone. This leads to abnormal bone marrow cavity formation and to the clinical signs and symptoms of bone marrow failure. It is accompanied by hepatosplenomegaly due to compensatory extramedullary hematopoiesis. The disease is heterogeneous. Over 50% of cases are due to mutations in the TCIRG1 gene and another 10% are due to mutations in the CLCN7 gene. A small number of patients have been described with mutations in the OSTM1 gene. Transmission is autosomal recessive. |

An extremely rare primary bone dysplasia with increased bone density disorder characterized by severe osteoclast-poor osteopetrosis associated with hypogammaglobulinemia. Patients typically present infantile malignant osteopetrosis (manifesting with increased bone density, bone fractures, abnormal eye movements/visual loss, nystagmus), hematologic abnormalities with bone marrow failure (for example anemia, hepatosplenomegaly) and immunological deficiency (manifesting as recurrent respiratory infections) associated with reduced immunoglobulin levels due to impaired peripheral B cell differentiation. There is evidence the disease is caused by homozygous or compound heterozygous mutation in the TNFRSF11A gene on chromosome 18q21. |

A rare syndromic optic nerve hypoplasia with characteristics of coloboma, osteopetrosis (particularly of the anterior ribs and femoral heads), severe microphthalmia, macrocephaly, albinism, and profound congenital deafness. Patients may also have additional eye anomalies including microcornea with pannus, dense bilateral cataracts, and translucent irides. Craniofacial dysmorphism (including frontal bossing, shallow orbits, preauricular pits, posteriorly rotated ears, micrognathia and wide palatine ridges) is also reported. |
