Genes affected

CUX1 (HGNC:2557): (cut like homeobox 1) The protein encoded by this gene is a member of the homeodomain family of DNA binding proteins. It may regulate gene expression, morphogenesis, and differentiation and it may also play a role in the cell cycle progession. Several alternatively spliced transcript variants encoding different isoforms have been identified.[provided by RefSeq, Feb 2011]

CUX1 Gene-Disease associations (from GenCC):

• global developmental delay with or without impaired intellectual development

  Inheritance: AD Classification: DEFINITIVE, STRONG, LIMITED Submitted by: Ambry Genetics, G2P, Labcorp Genetics (formerly Invitae)
• autosomal dominant non-syndromic intellectual disability

  Inheritance: AD Classification: SUPPORTIVE Submitted by: Orphanet

ACMG classification

Our verdict: Benign. The variant received -9 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.31950623).
• BS1: Variant frequency is greater than expected in population afr. GnomAdExome4 allele frequency = 0.00000684 (10/1461652) while in subpopulation AFR AF = 0.000149 (5/33476). AF 95% confidence interval is 0.0000585. There are 0 homozygotes in GnomAdExome4. There are 4 alleles in the male GnomAdExome4 subpopulation. Median coverage is 30. This position passed quality control check.
• BS2: High AC in GnomAdExome4 at 10 AD gene.
