Variant summary

Our verdict is Benign. Variant got -16 ACMG points: 0P and 16B. BP5_StrongBS2BA1

This summary comes from the ClinGen Evidence Repository: The allele frequency of the p.Pro198= variant in FOXG1 is 0.04% in African sub population in gnomAD v2.1.1, 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 p.Pro198= variant is observed in at least 2 unaffected individuals (GeneDx internal database) (BS2). The p.Pro198= variant is found in at least 3 patients with an alternate molecular basis of disease (GeneDx internal database) (BP5_strong). The p.Pro198= variant occurs in the well-characterized Forkhead functional domain of the FOXG1 gene; however, as this is a synonymous change, there would be no affect on the amino acid sequence of the functional domain (PM1 not met). In summary, the p.Pro198= variant in FOXG1 is classified as benign based on the ACMG/AMP criteria (BA1, BS2, BP5_strong).

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]
