Type II Gaucher disease: compound heterozygote with RecNciI and L444P mutations.
We report the phenotype and genotype of an Indonesian Chinese boy with type II Gaucher disease. He had a unique presentation of recurrent cyanosis from laryngospasm. He was compound heterozygous for L444P/L444P + A456P + V460V. There have been few reports of this heterozygosity and its phenoptype. This genotype-phenotype correlation will be important for physicians in genetic counselling. Type II Gaucher disease in Southeast Asia may not be as rare as was perceived, but may be a condition that is under-reported. The success of our technique together with the results have made it possible for us to perform prenatal diagnosis and carrier detection for the family.
