It is characterized by a series of classic features such as hypotonia, hyperphagia, obesity, osteoporosis, typical facial and body dysmorphosis, hypogonadism, mental and behaviour disorders. Our study was designed to precisely detect the microdeletions, which accounts for 65%-70% of the PWS. Methods Physical and laboratory examinations were firstly performed to diagnose PWS clinically, and to discover novel clinical features. Then the patient was screened with bisulfite-specific sequencing and precisely delineated through high-density array CGH. Results With the bisulfite-specific sequencing, the detected CpG island in the PWS critical region was found homozygously hypermethylated. Then with array CGH, a 2.22 Mb type II microdeletion was detected, covering a region from MKRN3, MAGEL2, NDN, PWRN2, PWRN1, Cl2orf2, SNURF-SNRPN, C/D snoRNAs, to distal of UBE3A. Conclusions Array CGH, after the fast screening of Bisulfite-specific sequencing, is a feasible and precise method to detect microdeletions in PWS patients. A novel feature of metacarpophalangeal joint rigidity was also presented, which is the first time reported in PWS.展开更多

Prader–Willi syndrome (PWS) is a rare genetic disorder caused by a loss of function of specific genes on chromosome 15. Patients with this disease present unique challenges in management, particularly regarding obesity and nutritional regulation as the disease symptoms change depending on the age of the patient and the phase of the disease. These challenges pose critical stressors to caregivers and their families. We present a case report of a 5-year-old Caucasian male diagnosed with PWS, exhibiting failure to thrive and uncontrolled weight gain. His caregiver was his elderly grandmother who, by her own admission, was ill-equipped to deal with the patient’s physical symptoms and his behavior in response to dietary restrictions. Through a multidisciplinary approach involving medical nutrition therapy (MNT) involving the implementation of a Consistent Individualized Carbohydrate-Controlled Anti-Inflammatory Nutritional plan (C-ICAN), growth hormone supplementation, and behavioral interventions patient markedly improved physically and emotionally.展开更多
