delayed bone age
Novel
genotypes and phenotypes among Chinese patients with Floating-Harbor syndrome. The wrist X-ray results of nine patients with FHS. These photos indicating the bone age delay in each patient. The chronological ages and corresponding bone ages are listed in Table 1
A generalized retardation in skeletal maturation has different causative or etiological factors, these can be classified as follows:
- chronic ill health
- congenital heart disease (especially cyanotic)
- chronic renal disease
- inflammatory bowel disease
- malnutrition: failure to thrive (FTT)
- rickets
- maternal deprivation
- intrauterine growth restriction (IUGR)
- infant of toxemic mother
- endocrine disorders
- hypothyroidism: cretinism and Van Wyk Grumbach syndrome
- hypopituitarism with growth hormone deficiency (e.g. idiopathic, craniopharyngioma)
- hypogonadism (e.g. Turner syndrome)
- Cushing disease / steroid therapy
- diabetes: juvenile
- Addison disease (adrenal insufficiency): uncommon
- hypoparathyroidism: uncommon
- systemic diseases
- chromosomal disorders
- congenital disorders
- congenital syndromes of dwarfism or intellectual disability
- Cleidocranial dysostosis
- neurologic disorders
- cerebral hypoplasia
- others: (normal variation)
- small for gestational age neonate
- idiopathic: familial short stature
