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 Pathogenic. Variant got 11 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 gene, where missense usually causes diseases (based on misZ statistic), FOXG1. . Trascript score misZ 3.7891 (greater than threshold 3.09). GenCC has associacion of gene with Rett syndrome, congenital variant, FOXG1 disorder.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.969
• PP5: Variant 14-28767992-G-A is Pathogenic according to our data. Variant chr14-28767992-G-A is described in ClinVar as [Likely_pathogenic]. Clinvar id is 435240.Status of the report is criteria_provided_single_submitter, 1 stars.
