Abstract
Microvillus inclusion disease (MVID, MIM♯ 251850), also known as congenital microvil-lus atrophy, was first described by Davidson et al. in 1978. It is a rare au-tosomal recessive disease that presents with an intractable life-threatening watery diarrhea either within the first days of life (early-onset form) or at several months of life (late-onset form) . The hallmarks of MVID are a lack of microvilli on the surface of villous enterocytes, occurrence of microvillous inclusions and the cytoplasmic accumulation of periodic acid-schiff-positive vesicles. In 2008, Muller et al showed that mutations in MYO5B (MIM ♯ 606540), en-coding the unconventional type Vb myosin motor protein, were associated with MVID in an ex-tended Turkish kindred. Since then, more mutations were described in different populations . In this report we describe a novel mutation in two unrelated Syrian patients with MVID.Keywords
