Wolf-Hirschhorn syndrome is a genomic disorder caused by 4p16.3 deletion with facial dysmorphology, growth retardation, developmental/intellectual delay and seizures. After 165 kb critical region encompassing NSD2 was identified, most recently, three NSD2 loss of function variants was uncovered in patients with overlapping phenotype with Wolf-Hirschhorn syndrome. In our study, a NSD2 variant, c.1577dupG (p.Asn527fs*14) was identified in two patie...

Objective: To report the clinical characteristics, diagnosis, treatment and genetic analysis of a case of X-linked acrogigantism(X-LAG).Methods: The clinical information of a 4-year-old girl due to “growth acceleration for 2.5 years, breast overflow for 3 months, accompanied by intermittent convulsions twice” was retrospectively reported, and peripheral blood DNA was collected for whole exome sequencing and e...

Objective: To explore the clinical features and the genetic cause of a multiple malformation patient with short stature.Methods: The clinical data was collected in Beijing Children’s Hospital in November 2017. The disease-causing variant was identified using exome sequencing and confirmed with Sanger sequencing. Related literature was searched from Wanfang and Pubmed databases using the key word of ‘PORCN gene’ to identify the clinical fea...
