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.

CUX2 Gene-Disease associations (from GenCC):

• developmental and epileptic encephalopathy, 67

  Inheritance: AD Classification: STRONG Submitted by: G2P, Labcorp Genetics (formerly Invitae), Ambry Genetics
• genetic developmental and epileptic encephalopathy

  Inheritance: AD Classification: MODERATE Submitted by: ClinGen
• Lennox-Gastaut syndrome

  Inheritance: AD Classification: SUPPORTIVE Submitted by: Orphanet

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.94).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.0589 is higher than 0.05.
