https://doi.org/10.1016/j.ejmg.2018.12.010 . Whole exome sequencing revealed novel pathogenic CAPN1 mutations in four patients from 3 families of Turkish, Japanese, and Punjabi descent and all were consanguineous. Onset in the four patients 20 and 37 years. Two also had mild ataxia. The phenotype of AR CAPN1 mutations appears to be spastic paraplegia with or without ataxia; onset commonly in adulthood. Eye movement abnormalities, skeletal defects, peripheral neuropathy and amyotrophy can sometimes be seenCreated: 28 Apr 2019, 4:16 p.m.
