Genes affected

CDC25A (HGNC:1725): (cell division cycle 25A) CDC25A is a member of the CDC25 family of phosphatases. CDC25A is required for progression from G1 to the S phase of the cell cycle. It activates the cyclin-dependent kinase CDC2 by removing two phosphate groups. CDC25A is specifically degraded in response to DNA damage, which prevents cells with chromosomal abnormalities from progressing through cell division. CDC25A is an oncogene, although its exact role in oncogenesis has not been demonstrated. Two transcript variants encoding different isoforms have been found for this gene.

ACMG classification

Classification was made for transcript

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

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.65).

BS1

Variant frequency is greater than expected in population sas. GnomAd4 allele frequency = 0.00503 (761/151152) while in subpopulation SAS AF = 0.0492 (236/4792). AF 95% confidence interval is 0.0441. There are 8 homozygotes in GnomAd4. There are 416 alleles in the male GnomAd4 subpopulation. Median coverage is 31. This position passed quality control check.

BS2

High AC in GnomAd4 at 761 AD gene.
