Variant summary

Our verdict is Benign. The variant received -8 ACMG points: 0P and 8B. BP4_StrongBS1

The NM_030928.4(CDT1):c.701G>C(p.Cys234Ser) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000217 in 1,612,854 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 16/22 in silico tools predict a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. C234R) has been classified as Benign.

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 was made for transcript

Our verdict: Benign. The variant received -8 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.012552649).

BS1

Variant frequency is greater than expected in population eas. GnomAdExome4 allele frequency = 0.0000212 (31/1460656) while in subpopulation EAS AF = 0.000781 (31/39696). AF 95% confidence interval is 0.000565. There are 0 homozygotes in GnomAdExome4. There are 16 alleles in the male GnomAdExome4 subpopulation. Median coverage is 69. This position passed quality control check.
