Genes affected

FOXF1 (HGNC:3809): (forkhead box F1) This gene belongs to the forkhead family of transcription factors which is characterized by a distinct forkhead domain. The specific function of this gene has not yet been determined; however, it may play a role in the regulation of pulmonary genes as well as embryonic development. [provided by RefSeq, Jul 2008]

FOXF1 NM_001451.2 exon 1 p.Gly18_Gly23dup (c.53_70dup): This variant has not been reported in the literature but is present in 1/8594 African alleles in the Genome Aggregation Database (http://gnomad.broadinstitute.org/). Evolutionary conservation and computational predictive tools for this variant are limited or unavailable. This variant represents an in-frame duplication resulting in the addition of 6 amino acids within a repeat region of glycines at position 18, and is not predicted to alter the reading frame. However, the effect of this variant on the protein is unclear. In summary, data on this variant is insufficient for disease classification. Therefore, the clinical significance of this variant is uncertain. -
