Genes affected

ADGRF1 (HGNC:18990): (adhesion G protein-coupled receptor F1) Predicted to enable G protein-coupled receptor activity. Predicted to be involved in G protein-coupled receptor signaling pathway. Predicted to act upstream of or within several processes, including memory; nervous system development; and positive regulation of CREB transcription factor activity. Predicted to be located in extracellular region and plasma membrane. Predicted to be integral component of membrane. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Likely_benign. Variant got -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.058366).

Collection Method: clinical testing

The c.2320G>A (p.V774I) alteration is located in exon 11 (coding exon 10) of the ADGRF1 gene. This alteration results from a G to A substitution at nucleotide position 2320, causing the valine (V) at amino acid position 774 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
