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: Benign. The variant received -10 ACMG points.

• BP6: Variant 14-28767055-CT-C is Benign according to our data. Variant chr14-28767055-CT-C is described in ClinVar as Likely_benign. ClinVar VariationId is 1188300.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.0109 (1522/139646) while in subpopulation AFR AF = 0.0337 (1291/38302). AF 95% confidence interval is 0.0322. There are 18 homozygotes in GnomAd4. There are 726 alleles in the male GnomAd4 subpopulation. Median coverage is 29. This position passed quality control check.
• BS2: High AC in GnomAd4 at 1522 AD gene.
