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]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -4 ACMG points.

PP2

Missense variant in gene, where missense usually causes diseases (based on misZ statistic), CUX1. . Gene score misZ 3.7492 (greater than the threshold 3.09). Trascript score misZ 3.103 (greater than threshold 3.09). GenCC has associacion of gene with global developmental delay with or without impaired intellectual development, autosomal dominant non-syndromic intellectual disability.

BS1

Variant frequency is greater than expected in population nfe. gnomad4_exome allele frequency = 0.000118 (172/1460138) while in subpopulation NFE AF= 0.000153 (170/1111990). AF 95% confidence interval is 0.000133. There are 0 homozygotes in gnomad4_exome. There are 93 alleles in male gnomad4_exome subpopulation. Median coverage is 31. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

BS2

High AC in GnomAd4 at 5 AD gene.

Ambry Genetics

Oct 26, 2022

The c.194C>G (p.A65G) alteration is located in exon 3 (coding exon 3) of the CUX1 gene. This alteration results from a C to G substitution at nucleotide position 194, causing the alanine (A) at amino acid position 65 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
