Variant summary

Our verdict is Likely benign. Variant got -5 ACMG points: 0P and 5B. BP5BS2

This summary comes from the ClinGen Evidence Repository: The p.Ser349Ala variant in FOXG1 is present in one XX and three XY individuals in gnomAD v2.1.1 (0.001418%) (not sufficient to meet BS1 criteria). The p.Ser349Ala variant is observed in at least 2 unaffected individuals (GeneDx internal database) (BS2). The p.Ser349Ala variant is found in a patient with an alternate molecular basis of disease (GeneDx internal database) (BP5). In summary, the p.Ser349Ala variant in FOXG1 is classified as likely benign based on the ACMG/AMP criteria (BS2, 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]

In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt FOXG1 protein function. ClinVar contains an entry for this variant (Variation ID: 205497). This variant has not been reported in the literature in individuals affected with FOXG1-related conditions. This variant is present in population databases (rs796052472, gnomAD 0.002%). This sequence change replaces serine, which is neutral and polar, with alanine, which is neutral and non-polar, at codon 349 of the FOXG1 protein (p.Ser349Ala). -
