Summary: | Abstract
Background
Cockayne syndrome (CS, OMIM #133540, #216400) is a rare autosomal recessive disease involving multiple systems, typically characterized by microcephaly, premature aging, growth retardation, neurosensory abnormalities, and photosensitivity. The age of onset is related to the severity of the clinical phenotype, which may lead to fatal outcomes.
Methods
We report a 3‐year‐old girl who presented with photosensitivity, gait abnormalities, stunting, and microcephaly and showed atypical clinical classification due to mild clinical manifestations at an early onset age.
Results
Next‐generation sequencing reveals the frameshift mutation (c.394_398del, p.Leu132Asnfs*6) and a novel microdeletion of
ERCC8
(exon4del, p.Arg92fs).
Conclusion
Therefore, it is still necessary to carry out next‐generation sequencing for CS patients with atypical clinical manifestations, which is essential for diagnosis and accurate genetic counseling. |
