Andermann syndrome, otherwise known as agenesis of the corpus callosum with peripheral neuropathy (ACCPN), is an autosomal recessive motor and sensory neuropathy known to be associated with ACC and mild-to-moderate intellectual disability. We present a 7-year-old girl with infantile-onset hypotonia, mild intellectual disability, and severe motor and sensory demyelinating peripheral neuropathy. Brain magnetic resonance imaging showed intact corpus callosum. Whole exome sequencing showed a novel splice-site pathogenic variant in the SLC12A6 gene. We confirm that ACC is not a mandatory feature and suggest that the term ACCPN may be misleading.
