Detailed entry for Gene:

U2af1rs1

Chromosome:

Human Chr5q22
Mouse Chr11 (proximal)

Links:

OMIM

Imprinting:

Maternal allele is silenced; paternal allele active. U2af1-rs1 is mprinted in mice (Shibata H et al, 1997; Hatada I et al, 1995) but not in humans (Pearsall RS et al, 1996).

Gene Product:

Sequence similarity to splicing factor U2af. U2af-rs1 is an intronless gene that may have arisen via retrotransposition (Nabetani A et al, 1997).

Functional Data:

Functional information for U2af1-rs1 is not available. Mice with maternal and paternal uniparental disomy for this imprinted region show growth retarded and overgrowth phenotypes, respectively (Cattanach BM et al, 1998).
