Next-generation sequencing through multi-gene panel testing for the diagnosis of a Chinese patient with atypical Cockayne syndrome.

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 n
