Abstract
BACKGROUND
Primrose syndrome is an autosomal dominant disorder characterized by craniofacial dysmorphism, mental retardation, developmental delay, progressive muscle atrophy and calcification of the earlobe due to a mutation in the ZBTB20.
METHOD
We reported a case of a Chinese boy with clinical symptoms resembling Primrose Syndrome, and performed genetic etiology analysis of the proband's family through Trio whole exome sequencing.
RESULT
A novel missense variant c.1927T>A(p.F643I) in exon 14 of the ZBTB20 (NM_001348803) was identified in the proband. This is the first report case of primrose syndrome in China, and our case extends the variant spectrum of ZBTB20 and further strengthens the understanding of primrose syndrome.
CONCLUSION
However, there are no formal clinical guidelines for the management of this disease, and research on treatment and prognosis remains a challenge and focus in future.
