Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_178861.5(RNF113B):c.80G>T(p.Arg27Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000498 in 1,607,128 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R27W) has been classified as Uncertain significance.

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]

RNF113B links:

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]

Ambry Genetics

May 27, 2022

The c.80G>T (p.R27L) alteration is located in exon 1 (coding exon 1) of the RNF113B gene. This alteration results from a G to T substitution at nucleotide position 80, causing the arginine (R) at amino acid position 27 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
