| Remarks |
The sample was originally submitted with an uncertain diagnosis of either severe Werner syndrome or mild Progeria. Additional information that was made available suggested that the patient should be classified as Werner syndrome with the comment that the distinction was arbitrary without a biochemical test. The sample was obtained when the child was 13 yr old. She had short stature and dysmorphic features. Physical examination showed large coarse brown freckles over the entire body, thin skin on hands and feet, clinodactyly of 4th and 5th digits of each hand and 4th digit of the right foot, bilateral simian creases and decreased flexion of fingers bilaterally. Chromosome examination was normal. Impression was of accelerated aging. Height was 137.2 cm (<5th percentile), Wt 26 kg (<5th percentile) and head circumference 51.1 cm (<2nd percentile). Dentition was poor, and spine had scoliosis. She has the atrophic skin changes, short stature, beak nose and high-pitched voice common to both progeria and Werner syndrome. Family history was unremarkable. This donor is heterozygous for an A-to-T substitution at nucleotide 1945 (1945A>T) in exon 11 of the LMNA gene, resulting in a missense mutation in codon 578 [GLU578VAL (E578V)]. |
