Genes affected

SREBF2 (HGNC:11290): (sterol regulatory element binding transcription factor 2) This gene encodes a member of the a ubiquitously expressed transcription factor that controls cholesterol homeostasis by regulating transcription of sterol-regulated genes. The encoded protein contains a basic helix-loop-helix-leucine zipper (bHLH-Zip) domain and binds the sterol regulatory element 1 motif. Alternate splicing results in multiple transcript variants.

ACMG classification

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=2.1461386E-5).
• BP6: Variant 22-41880738-G-C is Benign according to our data. Variant chr22-41880738-G-C is described in ClinVar as [Benign]. Clinvar id is 1285913.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.578 is higher than 0.05.
