Genetic Variant FOXE1:p.Ala174_Ala179del (chr9-97854418-AGCCGCCGCCGCCGCCGCC-A) – ACMG Classification: Likely_benign (-5 pts)

Variant summary

Our verdict is Likely benign. The variant received -5 ACMG points: 0P and 5B. BP3BS2

The NM_004473.4(FOXE1):c.520_537delGCCGCCGCCGCCGCCGCC(p.Ala174_Ala179del) variant causes a conservative inframe deletion change. The variant allele was found at a frequency of 0.000244 in 1,220,050 control chromosomes in the GnomAD database, including 4 homozygotes. It is difficult to determine the true allele frequency of this variant because it is of type DEL_BIG, and the frequency of such variant types in population databases may be underestimated and unreliable. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

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]
