A heterozygous mutation in the CCDC88C gene likely causes early-onset pure hereditary spastic paraplegia: a case report.

ABSTRACT:

Background

CCDC88C is a ubiquitously expressed protein with multiple functions, including roles in cell polarity and the development of dendrites in the nervous system. Bi-allelic mutations in the CCDC88C gene cause autosomal recessive congenital hydrocephalus (OMIM #236600). Studies recently linked heterozygous mutations in CCDC88C to the development of the late-onset spinocerebellar ataxia type 40 (OMIM #616053).

Case presentation

A 48-year-old Sudanese female presented with pure early onset hereditary spastic paraplegia. Exome sequencing, in-silico analysis, and Sanger sequencing identified the heterozygous NM_001080414.4:c.1993G > A (p.E665K) variant in CCDC88C as a potential cause of her illness. To explore the pathogenicity of the NM_001080414.4:c.1993G > A (p.E665K) v
