Hyperbilirubinemia, Rotor type (HBLRR)1 Publication
The disease is caused by variants affecting the gene represented in this entry.
Disease descriptionAn autosomal recessive form of primary conjugated hyperbilirubinemia. Affected individuals develop mild jaundice not associated with hemolysis shortly after birth or in childhood. They have delayed plasma clearance of the unconjugated anionic dye bromsulphthalein and prominent urinary excretion of coproporphyrin I. Hepatic pigmentation is normal.

<p>The checksum is a form of redundancy check that is calculated from the sequence. It is useful for tracking sequence updates.</p> <p>It should be noted that while, in theory, two different sequences could have the same checksum value, the likelihood that this would happen is extremely low.</p> <p>However UniProtKB may contain entries with identical sequences in case of multiple genes (paralogs).</p> <p>The checksum is computed as the sequence 64-bit Cyclic Redundancy Check value (CRC64) using the generator polynomial: x<sup>64</sup> + x<sup>4</sup> + x<sup>3</sup> + x + 1. The algorithm is described in the ISO 3309 standard. </p> <p class="publication">Press W.H., Flannery B.P., Teukolsky S.A. and Vetterling W.T.<br /> <strong>Cyclic redundancy and other checksums</strong><br /> <a href="http://www.nrbook.com/b/bookcpdf.php">Numerical recipes in C 2nd ed., pp896-902, Cambridge University Press (1993)</a>)</p> Checksum:i6D2AE371D782C7FB
