Novel PTEN mutation with leukoencephalopathy, basal ganglia calcification and action tremor

A 36-year-old security officer presented with a 2.5-year history of left upper limb tremor, which worsened on pouring water. There was no slowing of movements, lower limb tremor, or improvement with alcohol. His four-year-old daughter was born prematurely and had been investigated for developmental delay in walking after her 2nd birthday, general clumsiness/dyspraxia and macrocephaly. Examination of the proband revealed relative macrocephaly (head circumference 98th centile), mild dystonic posturing and position-specific left upper limb action tremor.
