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

Our verdict: Likely_benign. The variant received -3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.35).
• BP6: Variant 14-28767750-G-A is Benign according to our data. Variant chr14-28767750-G-A is described in ClinVar as Likely_benign. ClinVar VariationId is 1596653.Status of the report is criteria_provided_single_submitter, 1 stars.
• BP7: Synonymous conserved (PhyloP=3.18 with no splicing effect.
