Genes affected

FOXE1 (HGNC:3806): (forkhead box E1) This intronless gene encodes a protein that belongs to the forkhead family of transcription factors. Members of this family contain a conserved 100-amino acid DNA-binding 'forkhead' domain. The encoded protein functions as a thyroid transcription factor that plays a role in thyroid morphogenesis. Mutations in this gene are associated with the Bamforth-Lazarus syndrome, and with susceptibility to nonmedullary thyroid cancer-4. [provided by RefSeq, Nov 2016]

The c.118G>A (p.A40T) alteration is located in exon 1 (coding exon 1) of the FOXE1 gene. This alteration results from a G to A substitution at nucleotide position 118, causing the alanine (A) at amino acid position 40 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

clinical testing

The FOXE1 p.Ala40Thr variant was not identified in the literature nor was it identified in ClinVar or Cosmic. The variant was identified in dbSNP (ID: rs752273041) and in control databases in 2 of 56194 chromosomes at a frequency of 0.00003559 (Genome Aggregation Database March 6, 2019, v2.1.1). The variant was observed in the European (non-Finnish) population in 2 of 21346 chromosomes (freq: 0.000094), but was not observed in the African, Latino, Ashkenazi Jewish, East Asian, European (Finnish), Other, or South Asian populations. The p.Ala40 residue is not conserved in mammals and computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) do not suggest a high likelihood of impact to the protein; however, this information is not predictive enough to rule out pathogenicity. The variant occurs outside of the splicing consensus sequence and in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) do not predict a difference in splicing. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time. This variant is classified as a variant of uncertain significance. -
