14-28767485-C-T

Variant summary

Our verdict is Likely benign. Variant got -1 ACMG points: 3P and 4B. PM2 PP2 BP4_Moderate BP6_Moderate

The NM_005249.5(FOXG1):c.206C>T(p.Pro69Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. 13/20 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P69Q) 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]

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

ACMG classification

Verdict is Likely_benign. Variant got -1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant where missense usually causes diseases, FOXG1
• BP4: Computational evidence support a benign effect (MetaRNN=0.23010114).
• BP6: Variant 14-28767485-C-T is Benign according to our data. Variant chr14-28767485-C-T is described in ClinVar as [Likely_benign]. Clinvar id is 1304019.Status of the report is criteria_provided_single_submitter, 1 stars.
