Variant summary

Our verdict is Likely benign. Variant got -2 ACMG points: 2P and 4B. PM2BP4_Strong

The NM_016125.4(RNFT1):c.59G>A(p.Arg20Lys) variant causes a missense, splice region change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000563 in 1,599,020 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/21 in silico tools predict a benign outcome for this variant. 1/1 splice prediction tools predict no significant impact on normal splicing. Variant has been reported in ClinVar as Uncertain significance (★).

Genes affected

RNFT1 (HGNC:30206): (ring finger protein, transmembrane 1) Enables ubiquitin binding activity and ubiquitin protein ligase activity. Involved in positive regulation of ERAD pathway and protein autoubiquitination. Located in endoplasmic reticulum. [provided by Alliance of Genome Resources, Apr 2022]

TBC1D3P1-DHX40P1 (HGNC:42362): (TBC1D3P1-DHX40P1 readthrough, transcribed pseudogene) This locus represents naturally-occurring readthrough transcription that extends through two unprocessed pseudogenes, TBC1D3P1 (TBC1 domain family member 3 pseudogene 1) and DHX40P1 (DEAH-box helicase 40 pseudogene 1), to protein-coding RNFT1 (ring finger protein, transmembrane 1). The individual pseudogene loci are not curated as transcribed regions. The readthrough transcript likely does not encode a functional protein, since translation of the long open reading frames would render the transcript a candidate for nonsense-mediated decay (NMD).

Ambry Genetics

Nov 13, 2023

The c.59G>A (p.R20K) alteration is located in exon 2 (coding exon 2) of the RNFT1 gene. This alteration results from a G to A substitution at nucleotide position 59, causing the arginine (R) at amino acid position 20 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
