520 |a Objective: To investigate the clinical and genetic characteristics of a Chinese boy with Verheij syndrome and review the literature. Methods: The clinical and genetic data of a Chinese boy with Verheij syndrome, who was admitted to the Department of Pediatrics, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology in May 2017 were analyzed. Original papers on Verheij syndrome published up to January 2018 were retrieved at PubMed, Human Gene Mutation Database (HGMD), Online Mendelian Inheritance in Man(OMIM), CNKI and WanFang databases by using the key words "Verheij syndrome" and "PUF60" . Results: The male patient (at the age of 14 years and 3 months) visited us because of growth retardation for 13 years. Atrial septal defect was repaired at the age 3. Congenital amblyopia and hyperopia were diagnosed at the age 4. On physical examination, serious growth retardation and delayed psychomotor development was noted. His height was 142.5 cm (-3.26 SDS). He had poor academic performance at school. Facial features included: webbed neck, hypertelorism, down-slanting palpebral fissures, long philtrum, thin upper lip, and high palate. Palmar crease was found in the right hand. His bone age was 10 years. Growth hormone stimulation test indicated partial growth hormone deficiency (growth hormone (GH) peak 6.63 μg/L). The level of insulin like growth factor 1 (IGF1) and insulin like growth factor binding protein 3 (IGFBP3) was lower than normal, 73.20 μg/L and 2 500 μg/L respectively. Abdominal ultrasound showed that the volumes of bilateral kidneys were small. The size of the left and right kidney was 8.5 cm × 3.3 cm and 8.4 cm × 4.3 cm respectively. Karyotype was normal (46, XY). MRI of pituitary showed partial empty sella turcica. Ten genes associated with Noonan syndrome (PTPN11, SOS1, RASA2, KRAS, RAF1, NRAS, SHOC2, BRAF, RIT1, A2ML1) were analyzed and no genetic mutations were found. Whole exome-sequencing analysis identified a de novo heterozygous frame shift mutation of PUF60 gene (c.931_934del, P.P.T 311Qfs*47). According to ACMG guidelines in 2015, the mutation is pathogenic and has not been reported in the above databases. Conclusions: This is the first case report of Verheij syndrome caused by mutation of PUF60 gene in Chinese population. It is difficult to discriminate Verheij syndrome from Noonan syndrome, both have clinical manifestations such as severe growth retardation, psychomotor retardation, and congenital heart disease. In addition to Noonan syndrome, PUF60 genetic analysis was recommended for avoiding missed diagnosis with such clinical manifestations of patients
