Genes affected

RBPJL (HGNC:13761): (recombination signal binding protein for immunoglobulin kappa J region like) This gene encodes a member of the suppressor of hairless protein family. A similar protein in mouse is a transcription factor that binds to DNA sequences almost identical to that bound by the Notch receptor signaling pathway transcription factor recombining binding protein J. The mouse protein has been shown to activate transcription in concert with Epstein-Barr virus nuclear antigen-2. Alternative splicing results in multiple transcript variants.

ACMG classification

Verdict is Benign. Variant got -8 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.01323235).
• BS2: High AC in GnomAd at 13 AD gene.

The c.805G>A (p.V269I) alteration is located in exon 8 (coding exon 8) of the RBPJL gene. This alteration results from a G to A substitution at nucleotide position 805, causing the valine (V) at amino acid position 269 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
