Abstract: Wolfram syndrome is a progressive neurodegenerative disorder caused by an alteration in the WFS-1 gene, located on chromosome 4p16.1 and is characterized by the acronym DIDMOAD (Diabetes Insipidus, Diabetes Mellitus, Optic Atrophy, and Deafness). WFS-1 gene encodes for a transmembrane protein termed Wolframin found in the membrane of the endoplasmic reticulum.

Objetive: To explore the prenatal ultrasound phenotype and genetic basis of two fetuses with Wolf-Hirschhorn syndrome (WHS).

Methods: A retrospective analysis was conducted on the ultrasound imaging data of two fetuses suspected for WHS at the Prenatal Diagnostic Center of Qingyuan People's Hospital in July 2017 and August 2019, respectively. Amniotic fluid samples of the two fetuses were subjected to chromosomal karyotyping and chromosomal microarray analysis (CMA).

Article Synopsis
  • * The disorder is caused by mutations in a gene on chromosome 4p16, which produces a protein called wolframin, crucial for cellular functions related to insulin signaling and stress response.
  • * Currently, there are no specific treatments for WS1; however, early diagnosis and genetic counseling can help manage symptoms and extend care to affected families, highlighting the need for ongoing research to find new therapies.
