Identification of a large homozygous SPG21 deletion in a Chinese patient with Mast syndrome.


ABSTRACT: A 37-year old man presented a slight delay in early developmental milestones, cognitive decline, difficulty walking, cerebellar signs and extrapyramidal signs. Brain magnetic resonance imaging (MRI) showed a thin corpus callosum, cerebral atrophy, non-specific white-matter hyperintensity, and cerebellar atrophy. The genetic test revealed a putative homozygous deletion in SPG21 from exon 3 through exon 7, which was further validated by long-range primer-walking PCR. This is the first report of Chinese patient with Mast syndrome carrying a large homozygous SPG21 deletion.
