Description

Isolated growth hormone deficiency type III with agammaglobulinemia (IGHD3) is characterized by agammaglobulinemia and markedly reduced numbers of B cells, short stature, delayed bone age, and good response to treatment with growth hormone. Only few sporadic male cases have been reported so far with mutations in BTK, although the complete correlation of hypogammaglobulinemia and growth hormone deficiency inherited in an X-linked recessive pattern could not be addressed. PMID: 1880652; 7849697; 8013627. A newly discovered mutation in MEF (myeloid elf-1-like factor) might be responsible for the disease in a single family with four affected males and two obligate carrier females in three generations with no mutations in BTK or impaired function. PMID: 18180883

Management

Antiinfectious prophylaxis, including gammaglobulins, sometimes with prophylactic antibiotics and early and aggressive treatment of infections may be beneficial; Live viral vaccines should be avoided; Recognition and treatment of growth hormone deficiency may be beneficial.
