Copy Number Variations in a Case with Intractable Epilepsy, Intellectual Disability, and Hereditary Neuropathy with

None:
Some copy number variations (CNVs) in DNA are associated with the development of pathological phenotypes. Regarding the diagnosis of recurrent radial nerve palsies, a 73-year-old female patient with intractable epilepsy and intellectual disability was diagnosed with duplicated 15q11.1-11.2, in addition to a deletion of 17p12, causing hereditary neuropathy with liability to pressure palsies. CNVs in 15q11.1-11.2 have been reported in patients with schizophrenia and autism. Although CNVs are also sometimes seen in healthy individuals, duplicated 15q11.1-11.2 could be associated with CNS symptoms in this patient.

Comparing Copy Number Variations and SNPs
Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...
