Variant summary

Our verdict is Benign. The variant received -9 ACMG points: 0P and 9B. BP7BA1

This summary comes from the ClinGen Evidence Repository: The allele frequency of the p.Ala149= variant in FOXG1 is 0.227% in European (Non-Finnish) sub population in gnomAD, which is high enough to be classified as benign based on thresholds defined by the ClinGen Rett/Angelman-like Expert Panel for Rett/AS-like conditions (BA1). The silent p.Ala149= variant is not predicted to affect splicing using multiple computational tools and does not affect a highly conserved nucleotide (BP7). In summary, the p.Ala149= variant in FOXG1 is classified as benign based on the ACMG/AMP criteria (BA1, BP7). LINK:https://erepo.genome.network/evrepo/ui/classification/CA232483/MONDO:0100040/016

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. -

ClinGen Rett and Angelman-like Disorders Variant Curation Expert Panel

Significance:Benign

Review Status:reviewed by expert panel

Collection Method:curation

The allele frequency of the p.Ala149= variant in FOXG1 is 0.227% in European (Non-Finnish) sub population in gnomAD, which is high enough to be classified as benign based on thresholds defined by the ClinGen Rett/Angelman-like Expert Panel for Rett/AS-like conditions (BA1). The silent p.Ala149= variant is not predicted to affect splicing using multiple computational tools and does not affect a highly conserved nucleotide (BP7). In summary, the p.Ala149= variant in FOXG1 is classified as benign based on the ACMG/AMP criteria (BA1, BP7). -
