Genes affected

RNF113B (HGNC:17267): (ring finger protein 113B) Predicted to enable metal ion binding activity. Predicted to be involved in snoRNA splicing. Predicted to be part of U2-type spliceosomal complex. [provided by Alliance of Genome Resources, Apr 2022]

FARP1 (HGNC:3591): (FERM, ARH/RhoGEF and pleckstrin domain protein 1) This gene encodes a protein containing a FERM (4.2, exrin, radixin, moesin) domain, a Dbl homology domain, and two pleckstrin homology domains. These domains are found in guanine nucleotide exchange factors and proteins that link the cytoskeleton to the cell membrane. The encoded protein functions in neurons to promote dendritic growth. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Nov 2013]

ACMG classification

Our verdict: Uncertain_significance. The variant received 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.3263122).
