Genes affected
FOXG1 (HGNC:3811): (forkhead box G1) This locus encodes a member of the fork-head transcription factor family. The encoded protein, which functions as a transcriptional repressor, is highly expressed in neural tissues during brain development. Mutations at this locus have been associated with Rett syndrome and a diverse spectrum of neurodevelopmental disorders defined as part of the FOXG1 syndrome. This gene is disregulated in many types of cancer and is the target of multiple microRNAs that regulate the proliferation of tumor cells. [provided by RefSeq, Jul 2020]

Significance: Likely benign
Review Status: criteria provided, single submitter
Collection Method: clinical testing

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -

Significance: Likely benign
Review Status: reviewed by expert panel
Collection Method: curation

The c.234_236dup (p.Pro79_Pro80insPro) variant is observed in at least 2 unaffected individuals (GeneDx internal database)(BS2). The c.234_236dup variant is an in-frame duplication present in a repetitive region of FOXG1 (BP3). The c.234_236dup variant is found in a patient with an alternate molecular basis of disease (GeneDx internal database) (BP5). In summary, the c.234_236dup (p.Pro79_Pro80insPro) variant in FOXG1 is classified as likely benign based on the ACMG/AMP criteria (BS2, BP3, BP5). -
