Genes affected

CENPF (HGNC:1857): (centromere protein F) This gene encodes a protein that associates with the centromere-kinetochore complex. The protein is a component of the nuclear matrix during the G2 phase of interphase. In late G2 the protein associates with the kinetochore and maintains this association through early anaphase. It localizes to the spindle midzone and the intracellular bridge in late anaphase and telophase, respectively, and is thought to be subsequently degraded. The localization of this protein suggests that it may play a role in chromosome segregation during mitotis. It is thought to form either a homodimer or heterodimer. Autoantibodies against this protein have been found in patients with cancer or graft versus host disease. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Benign. Variant got -14 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.85).
• BP6: Variant 1-214614184-G-C is Benign according to our data. Variant chr1-214614184-G-C is described in ClinVar as [Likely_benign]. Clinvar id is 1218534.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population amr. gnomad4 allele frequency = 0.0172 (2479/144192) while in subpopulation AMR AF= 0.0241 (327/13556). AF 95% confidence interval is 0.023. There are 32 homozygotes in gnomad4. There are 1147 alleles in male gnomad4 subpopulation. Median coverage is 31. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd at 32 AR gene
