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

Verdict is Likely_pathogenic. Variant got 6 ACMG points.

• PM1: In a DNA_binding_region Fork-head (size 94) in uniprot entity FOXG1_HUMAN there are 38 pathogenic changes around while only 0 benign (100%) in NM_005249.5
• 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.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.832
