Genes affected

CUX2 (HGNC:19347): (cut like homeobox 2) This gene encodes a protein which contains three CUT domains and a homeodomain; both domains are DNA-binding motifs. A similar gene, whose gene product possesses different DNA-binding activities, is located on chromosome on chromosome 7. Two pseudogenes of this gene have been identified on chromosomes 10 and 4.

The c.238A>G (p.K80E) alteration is located in exon 4 (coding exon 4) of the CUX2 gene. This alteration results from a A to G substitution at nucleotide position 238, causing the lysine (K) at amino acid position 80 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
