Phenotypes associated with the disease isolated growth hormone deficiency type II (OMIM:173100):
- Severe short stature (HP:0003510): A severe degree of short stature, more than -4 SD from the mean corrected for age and sex. Evidence: PCS. Frequency: 1/1. (PMID:18554279)
- Scoliosis (HP:0002650): The presence of an abnormal lateral curvature of the spine. Evidence: PCS. Frequency: 1/1. (PMID:18554279)
- Anterior pituitary hypoplasia (HP:0010627): Underdevelopment of the anterior pituitary gland. Evidence: PCS. Frequency: 1/1. (PMID:18554279)
- Childhood onset (HP:0011463): Onset of disease at the age of between 1 and 5 years. Evidence: PCS. Frequency: 1/1. (PMID:18554279)
- Pituitary dwarfism (HP:0000839): A type of reduced stature with normal proportions related to dysfunction of the pituitary gland related to either an isolated defect in the secretion of growth hormone or to panhypopituitarism, i.e., a deficit of all the anterior pituitary hormones. Evidence: IEA. (OMIM:173100)
- Decreased circulating insulin-like growth factor 1 concentration (HP:0030353): The concentration of insulin-like growth factor 1 (IGF1) in the blood circulation is below the lower limit of normal. Evidence: PCS. Frequency: 1/1. (PMID:18554279)
- Decreased response to growth hormone stimulation test (HP:0000824): Insufficient responses to growth hormone (GH) provocation tests. GH deficiency is defined as a serum peak GH concentration less than 10 ng/mL on provocation with a combination of at least two separate stimulation tests. Evidence: PCS. Frequency: 1/1. (PMID:18554279)
- Autosomal dominant inheritance (HP:0000006): 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. Evidence: PCS. (PMID:18554279)
