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

Verdict is Benign. Variant got -8 ACMG points.

• BS1: Variant frequency is greater than expected in population eas. gnomad4 allele frequency = 0.000781 (115/147264) while in subpopulation EAS AF= 0.00279 (14/5016). AF 95% confidence interval is 0.00169. There are 0 homozygotes in gnomad4. There are 58 alleles in male gnomad4 subpopulation. Median coverage is 26. This position pass quality control queck.
• BS2: High AC in GnomAd4 at 115 AD gene.
