Abstract:
OBJECTIVE:Two brothes with Seckel's syndrome 1(SCKL1) were reported and a literature review was carried to provide clinical and genetic information of this rare disease.
METHODS:Clinical data of the two children were collected, and the peripheral blood was extracted for whole exome sequencing. Literature of the disease were reviewed.
RESULTS:The two patients were 11 years and 9.5 years old when examined for short stature. They presented with intrauterine growth retardation, intellectual disability, microcephaly, birdhead-like face and coffee au lait spots. The bone age was more than 2 years behind the chronical age and the growth hormone levels were normal. Whole exome sequencing revealed novel compound heterozygous variants c.1A>G (p.M1?) and c.4853-18A>G of ART gene in both children.
CONCLUSION:Children with prenatal onset short stature, developmental delay, microcephaly and special facial featuresshould be considered for the possibility of Seckel's syndrome, whole exome sequencing could help to confirm the clinical diagnosis.
