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

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=0.12829265).
• BP6: Variant 13-98176351-G-A is Benign according to our data. Variant chr13-98176351-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 3154957.Status of the report is criteria_provided_single_submitter, 1 stars.

Significance: Likely benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
