Andermann syndrome

An autosomal recessive condition characterised by motor and sensory neuropathy, agenesis of corpus callosum with neuropathy, areflexia, muscular hypotonia, muscle wasting, progressive weakness, tremors and regression of developmental milestones achieved by age 3–4, with scoliosis, gaze palsy and ptosis. Skeletal defects include ocular hypertelorism; widened, short skull (brachycephaly); high palatal arch; overriding great toe; syndactyly of second and third toes.

Molecular pathology
Andermann syndrome is caused by mutation in SLC12A6, which co-transports potassium and chloride across cell membranes.
