Genes affected

UBXN6 (HGNC:14928): (UBX domain protein 6) Involved in ERAD pathway; endosome to lysosome transport via multivesicular body sorting pathway; and macroautophagy. Located in bounding membrane of organelle and cytosol. Is extrinsic component of membrane. Part of endosome and protein-containing complex. [provided by Alliance of Genome Resources, Apr 2022]

CHAF1A (HGNC:1910): (chromatin assembly factor 1 subunit A) Chromatin assembly factor I (CAF1) is a nuclear complex consisting of p50, p60 (CHAF1B; MIM 601245), and p150 (CHAF1A) subunits that assembles histone octamers onto replicating DNA in vitro (Kaufman et al., 1995 [PubMed 7600578]).[supplied by OMIM, Mar 2008]

MIR4746 (HGNC:41904): (microRNA 4746) 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]

Collection Method: clinical testing

The c.1090G>T (p.G364W) alteration is located in exon 10 (coding exon 10) of the UBXN6 gene. This alteration results from a G to T substitution at nucleotide position 1090, causing the glycine (G) at amino acid position 364 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
