Current methods to isotype the poly-T region rely on long PCR, subcloning and sequencing to distinguish among the allelic variants. While such methods are extremely accurate as well as quantitative in determining the number of T residues in the poly-T region, the process can be cumbersome, time consuming and expensive to employ in routine laboratories. To this end, we have developed a quick and simple method to isotype the human TOMM40 variable length polymorphism using a PCR- and restriction digest-based approach, enabling rapid genotyping of TOMM40 variants.","tracks":[{"project":"Allie","denotations":[{"id":"SS1_22950840_1_0","span":{"begin":137,"end":191},"obj":"expanded"},{"id":"SS2_22950840_1_0","span":{"begin":193,"end":199},"obj":"abbr"}],"relations":[{"id":"AE1_22950840_1_0","pred":"abbreviatedTo","subj":"SS1_22950840_1_0","obj":"SS2_22950840_1_0"}],"attributes":[{"subj":"SS1_22950840_1_0","pred":"source","obj":"Allie"},{"subj":"SS2_22950840_1_0","pred":"source","obj":"Allie"}]},{"project":"PubmedHPO","denotations":[{"id":"T1","span":{"begin":158,"end":171},"obj":"HP_0001427"}],"attributes":[{"subj":"T1","pred":"source","obj":"PubmedHPO"}]}],"config":{"attribute types":[{"pred":"source","value type":"selection","values":[{"id":"Allie","color":"#e493ec","default":true},{"id":"PubmedHPO","color":"#93ecca"}]}]}}
