Background: Beta-ketothiolase deficiency is a rare autosomal recessive disease caused by ACAT1 gene mutation. Only 100 cases have been reported up to now.Methods: Among the 13 patients, four were diagnosed in our institute, and 9 were from a literature review of all reported Chinese cases. Two patients were diagnosed with newborn screening, and the others were diagnosed after ketoacidotic episodes. Clinical characteristics, laboratory and molecu...

Background: Given the absence of a systematic evaluation of general public’ attitudes towards the storage and use of newborn screening (NBS) blood samples for research in China, we firstly conducted this internet-based survey to explore these issues.Methods: We conducted a national-based internet survey with self-designed questionnaire. We mainly studied three categories: 1) the willingness to have their children’s residual NBS samples used for...

Background: Prader-Willi syndrome (PWS) is a rare complex genetic disorder caused by an absence of expression of imprinted genes on the paternally derived chromosome 15q11-q13 region. This study aimed to characterize the perinatal features in a cohort of Chinese individuals with PWS.Methods: We analyzed anonymous data of 134 patients from the PWS Registry in China. Perinatal and neonatal presentations were analyzed, and ...

Background: The Hedgehog (HH) family plays an important role in the development, proliferation and homeostasis in various tissues and organs. Desert hedgehog(DHH), as a member of this family, is mainly involved in the normal development of testis and the formation of nerve sheath. DHH variation mainly causes 46, XY disorders of sex development (DSD) with or without minifascicular neuropathy(MN). Up to date, only 22 affected patients in detail have bee...

Objective: This study was to measure quality of life (QOL) of the primary caregivers for young children with Prader-Willi syndrome (PWS).Methods: The children with PWS consisted of 32 children. The QOL of the caregiver for each patient was assessed using the Chinese version of the WHOQOL-BREF, and the Infants-Junior Middle School Students' Social-Life Abilities Scale was used to evaluate the social adaption capacity ...

Congenital lipoid adrenal hyperplasia (CLAH) is the most severe and extremely rare form of congenital adrenal hyperplasia (CAH). The typical features include 46, XY disorder of sex development (DSD), early-onset adrenal crisis and enlarged adrenal with fatty accumulation. We reported a case of congenital lipoid adrenal hyperplasia (CLAH) caused by steroidogenic acute regulatory protein (STAR) gene mutation. The patient had typical early-onset adrenal crisis at the age of 2 mon...

Objectives: To summarize the clinical manifestations of a patient of 46,XY partial gonadal dysgenesis (PGD) accompanied by neuropathy. This is the first reported case of DHH mutation from China.Methods: We retrospectively reviewed the case and summarized the clinical history, physical examinations, laboratory and genetics tests, electromyography, ultrasound, surgical exploration and histopathology results.Results: The 14.3-year-old...

Background: To construct the growth curves of body length and weight for Chinese patients from birth to 3 years with salt-wasting 21-hydroxylase deficiency (SW 21-OHD), changes in body mass index (BMI) will also be described, so as to explore the growth pattern of these special patients and guide the monitoring of early growth.Methods: The body length and weight data of SW 21-OHD patients aged 0-3 years who visited in 4 ...

Background: X-linked adrenal hypoplasia congenita (AHC) is a rare disorder characterized by primary adrenal insufficiency (PAI) and hypogonadotropic hypogonadism (HH), with limited clinical and genetic characterization.Methods: The clinical, biochemical, genetic, therapeutic, and follow-up data of 42 patients diagnosed with X-linked AHC were retrospectively analysed.Results: Hyperp...
