Fukuyama-type congenital muscular dystrophy: a case report in the Japanese population living in Brazil.
BACKGROUND
We present herein clinical, histological and magnetic resonance imaging (MRI) findings in a patient with Fukuyama-type congenital muscular dystrophy (FCMD). He is the first case report in the Japanese population living in Brazil.


METHODS
The child presented with neonatal hypotonia, delayed motor abilities and speech, seizures, cerebral and cerebellar gyrus abnormalities with signal intensity change in the white matter by MRI, high serum level of creatinephosphokinase (CK), and dystrophic skeletal muscle with normal merosin, alpha-sarcoglycan and dystrophin expression. The fukutin gene study showed one founder 3-kb retrotransposal insertion in the 3'-non-coding region, and in the other allele no mutation was detected after screening all exons and flanking introns by sequencing.


CONCLUSIONS
This case report emphasizes the importance to consider FCMD in Japanese people living in other countries.
