Variant summary

Our verdict is Benign. The variant received -13 ACMG points: 0P and 13B. BP4 BA1 BS2

This summary comes from the ClinGen Evidence Repository: The highest population minor allele frequency of the p.Gln70Pro variant in FOXG1 in gnomAD v4.1 is 0.00033 in the Admixed American population, which is higher than the ClinGen Rett and Angelman-like Disorders VCEP threshold (≥0.0003) for BA1, and therefore meets this criterion (BA1). The p.Gln70Pro variant is observed in at least 2 unaffected individuals (Internal database - Ambry) (BS2). Computational analysis prediction tools suggest that the p.Gln70Pro variant does not have a deleterious impact; however this information does not predict clinical significance on its own (BP4). In summary, the p.Gln70Pro variant in FOXG1 is classified as benign based on the ACMG/AMP criteria (BA1, BS2, BP4).

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]

LINC01551 (HGNC:19828): (long intergenic non-protein coding RNA 1551)
