Variant summary

Our verdict is Likely benign. Variant got -2 ACMG points: 1P and 3B. PM2_SupportingBP4BS2_SupportingBP5

This summary comes from the ClinGen Evidence Repository: The p.Ala92Val variant in FOXG1 is observed in at least 1 unaffected individual (internal database - Invitae) (BS2_supporting). The p.Ala92Val variant is found in at least 2 patients with an alternate molecular basis of disease (internal database - Invitae) (BP5). Computational analysis prediction tools suggest that the p.Ala92Val variant does not have a deleterious impact; however this information does not predict clinical significance on its own (BP4). The p.Ala92Val variant in FOXG1 is absent from gnomAD (PM2_supporting).In the absence of other pathogenic evidence beyond PM2_Supporting, and because this variant has been observed in 1 unaffected individual and 2 individuals with an alternate molecular diagnosis, the ClinGen Rett and Angelman-like Disorders Variant Curation Expert Panel has agreed to overrule the PM2_Supporting criterion and classified this variant as Likely Benign (BS2_supporting, BP4, BP5).

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]
