Abstract

Protocadherin 12 (PCDH12) is a member of a nonclustered group of cell surface proteins. Mutations in the PCDH12 gene can cause varied phenotypes ranging from epilepsy and movement disorders to congenital malformations and calcifications in neuroimaging. We discussed here a 14-year-old male patient with a movement disorder that mimicked dyskinetic cerebral palsy in the outpatient department; however, exome sequencing revealed a homozygous premature stop codon in exon 1 of the PCDH12(−) gene. The case highlights the importance of careful clinical examination to look for the features that do not match an assigned neurological syndrome and the need for follow-up neuroimaging to look for any progressive changes in all cases of unexplained movement disorder and intellectual impairment.
