摘要: level was influenced by the genotype of -Thal.conclusion, in acountry with high degree mis-cegenation such as Brazil, not only diagnosis doubleheterozygous states,suchasS- Thal,butalsothediagnosisofco-inheritance SCA -Thal should be carried out care-fully, taking into consideration limitations availablelaboratory techniques. Family studies or DNA analysis, whenpossible, are desirable to confirm correct diagnosis.
