Sequence of polymerase chain reaction products form patient blood samples. LAPTM4B*1 contains one 19 bp sequence (gray box), located in the promoter region (white box), following the transcription start site (double black lines) and prior to the open reading frame region (black box). LAPTM4B*2 contains two 19 bp sequences located at the same position. Sequencing results are presented below the gene structure display. LAPTM4B, lysosome-associated protein transmembrane 4-β.
