Genes affected

RNF2 (HGNC:10061): (ring finger protein 2) Polycomb group (PcG) of proteins form the multiprotein complexes that are important for the transcription repression of various genes involved in development and cell proliferation. The protein encoded by this gene is one of the PcG proteins. It has been shown to interact with, and suppress the activity of, transcription factor CP2 (TFCP2/CP2). Studies of the mouse counterpart suggested the involvement of this gene in the specification of anterior-posterior axis, as well as in cell proliferation in early development. This protein was also found to interact with huntingtin interacting protein 2 (HIP2), an ubiquitin-conjugating enzyme, and possess ubiquitin ligase activity. [provided by RefSeq, Jul 2008]

RNF2 Gene-Disease associations (from GenCC):

• Luo-Schoch-Yamamoto syndrome

  Inheritance: AD Classification: STRONG Submitted by: Labcorp Genetics (formerly Invitae)

ACMG classification

Our verdict: Uncertain_significance. The variant received 4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 1 curated pathogenic missense variants (we use a threshold of 10). The gene has 0 curated benign missense variants. Gene score misZ: 2.5248 (below the threshold of 3.09). Trascript score misZ: 2.9616 (below the threshold of 3.09). GenCC associations: The gene is linked to Luo-Schoch-Yamamoto syndrome.
• PP5: Variant 1-185091737-T-G is Pathogenic according to our data. Variant chr1-185091737-T-G is described in ClinVar as Pathogenic. ClinVar VariationId is 1189036.Status of the report is no_assertion_criteria_provided, 0 stars.
