Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 3P and 3B. PM2PP2BP4_ModerateBP6

The NM_005249.5(FOXG1):c.251C>G(p.Pro84Arg) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000136 in 147,192 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 12/20 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P84H) has been classified as Likely benign.

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]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 0 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=0.08721593).

BP6

Variant 14-28767530-C-G is Benign according to our data. Variant chr14-28767530-C-G is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 281382.We mark this variant Likely_benign, oryginal submissions are: {Benign=1, Uncertain_significance=1}.
