Genes Involved and Proteins

Gene name
NUP98 (nucleoporin 98 kDa)
Location
11p15.4
Protein description
Nucleoporin: associated with the nuclear pore complex. Role in nucleocytoplasmic transport processes.
Gene name
SETBP1 (SET binding protein 1)
Location
18q12.3
Protein description
Contains 3 DNA binding domains (A.T hooks). SETBP1 protects SET from protease cleavage. SETBP1 forms a complex with SET and PP2A (protein phosphatase 2A). SETBP1 impairs PP2A activity via SET and promotes proliferation of acute myeloid leukemia cells (Cristóbal et al., 2010).
Germinal mutations
In Schinzel-Giedion midface retraction syndrome.

Result of the Chromosomal Anomaly

Description

5 NUP98 - 3 SETBP1

Transcript

Exon 12 of NUP98 (nucleotide (nt) 1552) fused in-frame with exon 5 of SETBP1 (nt 4015).
