Genes affected

RAPGEFL1 (HGNC:17428): (Rap guanine nucleotide exchange factor like 1) Predicted to enable guanyl-nucleotide exchange factor activity. Predicted to be involved in G protein-coupled receptor signaling pathway and nervous system development. Predicted to be located in membrane. [provided by Alliance of Genome Resources, Apr 2022]

RAPGEFL1 links:

MIR6867 (HGNC:50134): (microRNA 6867) microRNAs (miRNAs) are short (20-24 nt) non-coding RNAs that are involved in post-transcriptional regulation of gene expression in multicellular organisms by affecting both the stability and translation of mRNAs. miRNAs are transcribed by RNA polymerase II as part of capped and polyadenylated primary transcripts (pri-miRNAs) that can be either protein-coding or non-coding. The primary transcript is cleaved by the Drosha ribonuclease III enzyme to produce an approximately 70-nt stem-loop precursor miRNA (pre-miRNA), which is further cleaved by the cytoplasmic Dicer ribonuclease to generate the mature miRNA and antisense miRNA star (miRNA*) products. The mature miRNA is incorporated into a RNA-induced silencing complex (RISC), which recognizes target mRNAs through imperfect base pairing with the miRNA and most commonly results in translational inhibition or destabilization of the target mRNA. The RefSeq represents the predicted microRNA stem-loop. [provided by RefSeq, Sep 2009]

The c.1271A>G (p.N424S) alteration is located in exon 15 (coding exon 13) of the RAPGEFL1 gene. This alteration results from a A to G substitution at nucleotide position 1271, causing the asparagine (N) at amino acid position 424 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
