dc.description.abstractObjective To investigate the possible involvement of germline mutations in a neurologic condition involving diffuse white matter lesions. Methods The patients were 3 siblings born to healthy parents. We performed homozygosity mapping, whole-exome sequencing, site-directed mutagenesis, and immunoblotting. Results All 3 patients showed clinical manifestations of ataxia, behavioral and mood changes, premature hair loss, memory loss, and lower back pain. In addition, they presented with inflammatory-like features and recurrent rhinitis. MRI showed abnormal diffuse demyelination lesions in the brain and myelitis in the spinal cord. We identified an insertion in high-temperature requirement A (HTRA1), which showed complete segregation in the pedigree. Functional analysis showed the mutation to affect stability and secretion of truncated protein. Conclusions The patients’ clinical manifestations are consistent with cerebral autosomal recessive arteriopathy with subcortical infarcts and leukoencephalopathy (CARASIL; OMIM #600142), which is known to be caused by HTRA1 mutations. Because some aspects of the clinical presentation deviate from those reported for CARASIL, our study expands the spectrum of clinical consequences of loss-of-function mutations in HTRA1.
