摘要

Johanson-Blizzard syndrome (JBS) is a rare autosomal recessive genetic disorder, characterized by exocrine pancreatic insufficiency, a distinct abnormal facial appearance and varying degrees of growth retardation. Ubiquitin protein ligase E3 component n-recognin 1 (UBR1) gene mutations are responsible for the syndrome. Here, we describe a 2-month-old female infant, who presented with oily diarrhea, facial dysmorphia, scalp defect, hearing defects, and growth impairment. Molecular genetic testing revealed a novel frameshift mutation in UBR1, c.4027_4028 del (p. Leu1343Valfs*7), which was not previously described in JBS in the literature.
