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 Benign. Variant got -18 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.33).
• BP6: Variant 14-28768762-C-A is Benign according to our data. Variant chr14-28768762-C-A is described in ClinVar as [Benign]. Clinvar id is 95263.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr14-28768762-C-A is described in Lovd as [Benign].
• BS1: Variant frequency is greater than expected in population amr. gnomad4 allele frequency = 0.0128 (1944/152174) while in subpopulation AMR AF= 0.0251 (383/15280). AF 95% confidence interval is 0.023. There are 15 homozygotes in gnomad4. There are 949 alleles in male gnomad4 subpopulation. This position pass quality control queck.
• BS2: High AC in GnomAd at 1944 AD gene.
