Mowat-Wilson syndrome with Hirschsprung′s disease and vaginal atresia: case report and literature review / 中华实用儿科临床杂志

ABSTRACT

Clinical phenotypes and gene characteristics of a patient diagnosed with Mowat-Wilson syndrome (MWS) with Hirschsprung′s disease (HSCR) and vaginal atresia in the Department of Neonatal Surgery, Beijing Children′s Hospital, Capital Medical University in March 2021 were analyzed retrospectively.The eight-month-old girl was admitted to the hospital with symptoms of constipation for nine days and abdominal distension for two days.Lower digestive tract radiography and rectal mucosa biopsy results suggested HSCR.The child also had specific facial features and motor development delay.Whole exome test showed a de novo heterozygous mutation, ZEB2 gene c. 2761C>T (p.R921*). After laparoscopic-assisted Soave procedure, the child had normal bowel movements, and no surgery-related compli-cations occurred during the follow-up period.The child′s motor development improved after rehabilitation treatment.According to literature review, 2 female cases show similar clinical manifestations to this girl, but the genotypes were different.This patient expands the clinical phenotype of ZEB2 gene pathogenicity.
