摘要:	Mutations in the MID1 gene result in X-linked Opitz G/BBB syndrome (OS), a disorder that affects development of midline structures and comprises hypertelorism, cleft lip/palate, hypospadias, and laryngo-tracheo-esophageal abnormalities, and, at times, neurological, anal, and cardiac defects. MID1 gene abnormalities include missense, nonsense, and splicing mutations, small insertions, small deletions, and complex rearrangements. Here, we present a patient with Opitz G/BBB syndrome and a unique MID1 gene point mutation c.1703T<C (p. Ile568Thr) in exon 10. This mutation was located in the loop between β5 and β6 beta pleated sheets in the SPRY domain. According to our 3D models based on the PRY-SPRY domain of the human TRIM72, the I568T mutation altered the conformation in the loops between β5 and β6 and between β7 and β8. Thus, the I568T mutation altered the conformation of surface B of the binding pocket and may affect the binding affinity to the PRY domain. Copyright © 2012 Wiley Periodicals, Inc.
