Genes affected

LOC100506403 (HGNC:):

RUNX1 (HGNC:10471): (RUNX family transcription factor 1) Core binding factor (CBF) is a heterodimeric transcription factor that binds to the core element of many enhancers and promoters. The protein encoded by this gene represents the alpha subunit of CBF and is thought to be involved in the development of normal hematopoiesis. Chromosomal translocations involving this gene are well-documented and have been associated with several types of leukemia. Three transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.9).
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00922 (1402/152124) while in subpopulation AFR AF= 0.0328 (1362/41496). AF 95% confidence interval is 0.0314. There are 35 homozygotes in gnomad4. There are 671 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 35 gene
