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)

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 1 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in the FOXG1 gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 90 curated pathogenic missense variants (we use a threshold of 10). The gene has 66 curated benign missense variants. Trascript score misZ: 3.7891 (above the threshold of 3.09). GenCC associations: The gene is linked to Rett syndrome, congenital variant, FOXG1 disorder.
BP4
Computational evidence support a benign effect (MetaRNN=0.20249116).

Review Status: criteria provided, single submitter
Collection Method: clinical testing

Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis indicates that this missense variant does not alter protein structure/function; De novo variant with confirmed parentage in a patient referred for genetic testing at GeneDx; however, the reported clinical features are only partially consistent with the features typically observed in individuals with pathogenic variants in this gene; Has not been previously published as pathogenic or benign to our knowledge -
