Genes affected
SLC2A9 (HGNC:13446): (solute carrier family 2 member 9) This gene encodes a member of the SLC2A facilitative glucose transporter family. Members of this family play a significant role in maintaining glucose homeostasis. The encoded protein may play a role in the development and survival of chondrocytes in cartilage matrices. Two transcript variants encoding distinct isoforms have been identified for this gene. [provided by RefSeq, Jul 2008]
SLC2A9-AS1 (HGNC:40636): (SLC2A9 antisense RNA 1)

This sequence change creates a premature translational stop signal (p.Ile119Hisfs*27) in the SLC2A9 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in SLC2A9 are known to be pathogenic (PMID: 19926891, 21256783, 21536615, 24628802). This variant is present in population databases (rs772429581, gnomAD 0.005%). This premature translational stop signal has been observed in individual(s) with clinical features of renal hypouricemia (PMID: 21256783). This variant is also known as p.I118HfsX27. ClinVar contains an entry for this variant (Variation ID: 350238). For these reasons, this variant has been classified as Pathogenic. -
