Abstrakt: Objective: To identify TUBB3 gene mutations in a Chinese family with congenital fibrosis of the extraocular muscle associated with corpus callosum agenesis.
Methods: We have found a family with CFEOM associated with corpus callosum agenesis, including 4 affected individuals in three generations of 11 familial members. 4 affected individuals were sequenced by direct TUBB3 sequencing, 4 unaffected individuals in the family and 100 cases of unrelated normal person as a control.
Results: This family is in line with Mendelian autosomal dominant inheritance. Clinical manifestations belongs to CFEOM3. All affected individuals were detected with TUBB3 c.1249G > A mutation, the mutation is in exon 4, resulting in wild-type gene encoding the Aspartic acid ( Asp or D ) replaced .by Asparagine (Asn or N ).
Conclusion: Our study supports that TUBB3 gene mutation c.1249G > A (p. Asp417Asn), is the underlying molecular pathogenesis of this family with CFEOM3.
