Genes affected

FOXP1 (HGNC:3823): (forkhead box P1) This gene belongs to subfamily P of the forkhead box (FOX) transcription factor family. Forkhead box transcription factors play important roles in the regulation of tissue- and cell type-specific gene transcription during both development and adulthood. Forkhead box P1 protein contains both DNA-binding- and protein-protein binding-domains. This gene may act as a tumor suppressor as it is lost in several tumor types and maps to a chromosomal region (3p14.1) reported to contain a tumor suppressor gene(s). Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Jul 2008]

ACMG classification

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

• BS1: Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.000736 (105/142692) while in subpopulation AFR AF = 0.00305 (103/33748). AF 95% confidence interval is 0.00257. There are 1 homozygotes in GnomAd4. There are 49 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
• BS2: High AC in GnomAd4 at 105 AD gene.
