Name

LINC00850:long intergenic non-protein coding RNA 850(HGNC nomenclature)

KUCG1[1]

Characteristics

Schematic description of the gene and X-chromosome [1].

LINC00850(alse named KUCG1) spans nearly 50kb onXq28 and is located 9.0kb downstream of MAGEA1 and 4.4kb upstream of MAGEA8. It has three exons separated by two introns(32kb and 20kb long, respectively). Its intron 1 encompassed the site of recombination of the intrachromosomal inversion inv(X)(p21.2; q28), which cause a a head-to-tail fusion of KUCG1 and dystrophin at the recombination sites. Exon 3 of KUCG1 overlaps with antisense transcript RP5-869M20.2, an lncRNA of unknown function.[1]

It belongs to the category of "Intergenic" in lncRNA classification.

Function

KUCG1 disruption may responsible for the moderate mental retardation in the index case as it was expressed in the brain.[1].

Diseases

  • Duchenne muscular dystrophy

Expression

KUCG1 was specially expressed in brain.[1]
