Growth and Final Height Among Children With Phenylketonuria.

Background And Objectives: Growth is an important criterion to evaluate health in childhood and adolescence, especially in patients depending on special dietary treatment. Phenylketonuria (PKU) is the most common inherited disease of amino acid metabolism. Patients with PKU depend on a special phenylalanine-restricted diet, low in natural protein.

Low-level hyperinsulinism with hypoglycemic spells in an infant with mosaic Turner syndrome and mild Kabuki-like phenotype: a case report and review of the literature.

Background: Impaired glucose tolerance and type 2 diabetes are well-known features in patients with Turner syndrome. To the best of our knowledge, there is only one reported case of hyperinsulinemic hypoglycemia associated with a complex mosaic Turner syndrome available in the current literature.

Patient: We report on the case of a 13-month-old girl with a complex mosaic Turner genotype and mild hyperinsulinemic hypoglycemia responsive to diazoxide therapy.

Transition of young adults with phenylketonuria from pediatric to adult care.

Background: Transition from pediatric to adult health care is a particularly vulnerable period for patients with inborn metabolic diseases. Aim of the present study was to evaluate the current transition situation of patients with phenylketonuria (PKU) in Leipzig, Germany, by analysis of the medical care, metabolic control, patients' satisfaction, socio-economic and psychosocial status, in order to identify areas of weakness and potential improvement.

Methods: Patients who had been transferred from pediatric to adult medical care between 2005 and 2008 were identified.

Deletion and point mutations of PTHLH cause brachydactyly type E.

Autosomal-dominant brachydactyly type E (BDE) is a congenital limb malformation characterized by small hands and feet predominantly as a result of shortened metacarpals and metatarsals. In a large pedigree with BDE, short stature, and learning disabilities, we detected a microdeletion of approximately 900 kb encompassing PTHLH, the gene coding for parathyroid hormone related protein (PTHRP). PTHRP is known to regulate the balance between chondrocyte proliferation and the onset of hypertrophic differentiation during endochondral bone development.

A case of maternal PKU syndrome despite intensive patient counseling.

We report on a 21-year-old woman with classic phenylketonuria, who presented at our outpatient clinic at week 14 of pregnancy. Despite intensive preconceptional counselling about the risk of raised Phenylalanine (Phe) levels for the offspring and nutritional consultations about the necessity to be on a Phe-restricted diet she had elevated blood Phe concentrations. Phe level could be lowered to the recommended range during a stay as an inpatient, but the patient was not able to maintain the recommended levels due to non-compliance.

Three novel missense mutations within the LHX4 gene are associated with variable pituitary hormone deficiencies.

Context: The LHX4 LIM-homeodomain transcription factor has essential roles in pituitary gland and nervous system development. Heterozygous mutations in LHX4 are associated with combined pituitary hormone deficiency.

Objectives: Our objectives were to determine the nature and frequency of LHX4 mutations in patients with pituitary hormone deficiency and to examine the functional outcomes of observed mutations.

PROP1 mutations cause progressive deterioration of anterior pituitary function including adrenal insufficiency: a longitudinal analysis.

Mutations in the PROP1 gene are the most frequent genetic defects in patients with combined pituitary hormone insufficiency. However, controversy exists about the timing and extent of pituitary insufficiency, and it remains unclear whether adrenal failure is a typical feature of this condition. We performed a retrospective longitudinal analysis of nine patients with PROP1 mutations who were under medical supervision at our clinic for 15.
