Genes affected
CDT1 (HGNC:24576): (chromatin licensing and DNA replication factor 1) The protein encoded by this gene is involved in the formation of the pre-replication complex that is necessary for DNA replication. The encoded protein can bind geminin, which prevents replication and may function to prevent this protein from initiating replication at inappropriate origins. Phosphorylation of this protein by cyclin A-dependent kinases results in degradation of the protein. [provided by RefSeq, Mar 2011]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -21 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.69).
BP6
Variant 16-88805775-C-T is Benign according to our data. Variant chr16-88805775-C-T is described in ClinVar as [Likely_benign]. Clinvar id is 210650.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BP7
Synonymous conserved (PhyloP=-3.89 with no splicing effect.
BS1
Variant frequency is greater than expected in population sas. gnomad4 allele frequency = 0.000958 (146/152350) while in subpopulation SAS AF= 0.0292 (141/4834). AF 95% confidence interval is 0.0252. There are 4 homozygotes in gnomad4. There are 103 alleles in male gnomad4 subpopulation. Median coverage is 35. This position pass quality control queck.
BS2
High Homozygotes in GnomAd4 at 4 AR gene
