Hartnup disorder (HND)5 Publications
The disease is caused by variants affecting the gene represented in this entry.
Disease descriptionAutosomal recessive abnormality of renal and gastrointestinal neutral amino acid transport noted for its clinical variability. First described in 1956, HND is characterized by increases in the urinary and intestinal excretion of neutral amino acids. Individuals with typical Hartnup aminoaciduria may be asymptomatic, some develop a photosensitive pellagra-like rash, attacks of cerebellar ataxia and other neurological or psychiatric features. Although the definition of HND was originally based on clinical and biochemical abnormalities, its marked clinical heterogeneity has led to it being known as a disorder with a consistent pathognomonic neutral hyperaminoaciduria.

Hyperglycinuria (HG)1 Publication
The disease may be caused by variants affecting the gene represented in this entry. SLC6A19 deficiency combined with haploinsufficiency of SLC6A20 or partially inactivating mutations in SLC36A2, can be responsible for hyperglycinuria.
Disease descriptionA condition characterized by excess of glycine in the urine. In some cases it is associated with renal colic and renal oxalate stones.

Iminoglycinuria (IG)1 Publication
The disease may be caused by variants affecting the gene represented in this entry. SLC6A19 deficiency combined with haploinsufficiency of SLC6A20 or partially inactivating mutations in SLC36A2, can be responsible for iminoglycinuria. Additional polymorphisms and mutations in SLC6A18 can contribute to the IG phenotype in some families.
Disease descriptionA disorder of renal tubular reabsorption of glycine and imino acids (proline and hydroxyproline), marked by excessive levels of all three substances in the urine.

<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.
