Genes affected

KXD1 (HGNC:28420): (KxDL motif containing 1) Involved in lysosome localization. Part of BORC complex. [provided by Alliance of Genome Resources, Apr 2022]

KXD1 links:

UBA52 (HGNC:12458): (ubiquitin A-52 residue ribosomal protein fusion product 1) Ubiquitin is a highly conserved nuclear and cytoplasmic protein that has a major role in targeting cellular proteins for degradation by the 26S proteosome. It is also involved in the maintenance of chromatin structure, the regulation of gene expression, and the stress response. Ubiquitin is synthesized as a precursor protein consisting of either polyubiquitin chains or a single ubiquitin moiety fused to an unrelated protein. This gene encodes a fusion protein consisting of ubiquitin at the N terminus and ribosomal protein L40 at the C terminus, a C-terminal extension protein (CEP). Multiple processed pseudogenes derived from this gene are present in the genome. [provided by RefSeq, Jul 2008]

Collection Method:clinical testing

The c.392C>T (p.T131M) alteration is located in exon 6 (coding exon 4) of the KXD1 gene. This alteration results from a C to T substitution at nucleotide position 392, causing the threonine (T) at amino acid position 131 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
