Short stature due to growth hormone qualitative anomaly

MedGen UID:
340412
Concept ID:
C1849779
Disease or Syndrome
Synonyms: Biodefective growth hormone; Kowarski syndrome; Pituitary dwarfism with normal immunoreactive growth hormone and low somatomedin
Modes of inheritance:
Autosomal recessive inheritance
MedGen UID:
141025
Concept ID:
C0441748
Intellectual Product
Source: Orphanet
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 individuals with two pathogenic alleles, either homozygotes (two copies of the same mutant allele) or compound heterozygotes (whereby each copy of a gene has a distinct mutant allele).
 
Gene (location): GH1 (17q23.3)
 
Monarch Initiative: MONDO:0009879
OMIM®: 262650
Orphanet: ORPHA629

Definition

Kowarski syndrome, or short stature associated with bioinactive growth hormone, is characterized clinically by normal or slightly increased GH secretion, pathologically low IGF1 (147440) levels, and normal catch-up growth on GH replacement therapy (Besson et al., 2005). [from OMIM]

Clinical features

From HPO
Pituitary dwarfism
MedGen UID:
8506
Concept ID:
C0013338
Disease or Syndrome
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.
Growth delay
MedGen UID:
99124
Concept ID:
C0456070
Pathologic Function
A deficiency or slowing down of growth pre- and postnatally.
Delayed skeletal maturation
MedGen UID:
108148
Concept ID:
C0541764
Finding
A decreased rate of skeletal maturation. Delayed skeletal maturation can be diagnosed on the basis of an estimation of the bone age from radiographs of specific bones in the human body.
Abnormality of metabolism/homeostasis
MedGen UID:
867398
