Genes affected

RING1 (HGNC:10018): (ring finger protein 1) This gene belongs to the RING finger family, members of which encode proteins characterized by a RING domain, a zinc-binding motif related to the zinc finger domain. The gene product can bind DNA and can act as a transcriptional repressor. It is associated with the multimeric polycomb group protein complex. The gene product interacts with the polycomb group proteins BMI1, EDR1, and CBX4, and colocalizes with these proteins in large nuclear domains. It interacts with the CBX4 protein via its glycine-rich C-terminal domain. The gene maps to the HLA class II region, where it is contiguous with the RING finger genes FABGL and HKE4.

ACMG classification

Verdict is Uncertain_significance. Variant got 2 ACMG points.

• PM1: In a modified_residue Phosphoserine (size 0) in uniprot entity RING1_HUMAN
• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.24672374).

The c.760A>C (p.S254R) alteration is located in exon 5 (coding exon 4) of the RING1 gene. This alteration results from a A to C substitution at nucleotide position 760, causing the serine (S) at amino acid position 254 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
