Autosomal dominant inheritance refers to genetic conditions that occur when a mutation is present in one copy of a given gene (i.e., the person is heterozygous).
Autosomal dominant inheritance
MedGen UID:
892334
Concept ID:
CN000007
Functional Concept
Source: HPO
A mode of inheritance that is observed for traits related to a gene encoded on one of the autosomes (i.e., the human chromosomes 1-22) in which a trait manifests in heterozygotes. In the context of medical genetics, an autosomal dominant disorder is caused when a single copy of the mutant allele is present. Males and females are affected equally, and can both transmit the disorder with a risk of 50% for each child of inheriting the mutant allele.

Definition

Osteoglophonic dysplasia is a condition characterized by abnormal bone growth that leads to severe head and face (craniofacial) abnormalities, dwarfism, and other features. The term osteoglophonic refers to the bones (osteo-) having distinctive hollowed out (-glophonic) areas that appear as holes on x-ray images.Premature fusion of certain bones in the skull (craniosynostosis) typically occurs in osteoglophonic dysplasia. The craniosynostosis associated with this disorder may give the head a tall appearance, often referred to in the medical literature as a tower-shaped skull, or a relatively mild version of a deformity called a cloverleaf skull. Characteristic facial features in people with osteoglophonic dysplasia include a prominent forehead (frontal bossing), widely spaced eyes (hypertelorism), flattening of the bridge of the nose and of the middle of the face (midface hypoplasia), a large tongue (macroglossia), a protruding jaw (prognathism), and a short neck. People with this condition usually have no visible teeth because the teeth never emerge from the jaw (clinical anodontia). In addition, the gums are often overgrown (hypertrophic gingiva).Infants with osteoglophonic dysplasia often experience failure to thrive, which means they do not gain weight and grow at the expected rate. Affected individuals have short, bowed legs and arms and are short in stature. They also have flat feet and short, broad hands and fingers.The life expectancy of people with osteoglophonic dysplasia depends on the extent of their craniofacial abnormalities; those that obstruct the air passages and affect the mouth and teeth can lead to respiratory problems and cause difficulty with eating and drinking. Despite the skull abnormalities, intelligence is generally not affected in this disorder.

Abnormality of bone mineral density
MedGen UID:
428073
Concept ID:
CN003849
Finding
This term applies to all changes in bone mineral density which (depending on severity) can be seen on x-rays as a change in density and or structure of the bone. Changes may affect all bones of the organism, just certain bones or only parts of bones and include decreased mineralisation as may be seen in osteoporosis or increased mineralisation and or ossification as in osteopetrosis, exostoses or any kind of atopic calicfications of different origin and distribution. The overall amount of mineralization of the bone-organ can be measured as the amount of matter per cubic centimeter of bones, usually measured by densitometry of the lumbar spine or hip. The measurements are usually reported as g/cm3 or as a Z-score (the number of standard deviations above or below the mean for the patient's age and sex). Note that measurement with this method does not reflect local changes in other bones, and as such might not be correct with regard the hole bone-organ.
