Genes affected

DTX3L (HGNC:30323): (deltex E3 ubiquitin ligase 3L) Enables several functions, including STAT family protein binding activity; ubiquitin-like protein ligase binding activity; and ubiquitin-protein transferase activity. Involved in several processes, including positive regulation of macromolecule metabolic process; positive regulation of protein localization; and protein ubiquitination. Located in cytosol; lysosome; and nucleoplasm. Part of protein-containing complex. Colocalizes with early endosome and nucleus. [provided by Alliance of Genome Resources, Apr 2022]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.752C>T (p.P251L) alteration is located in exon 3 (coding exon 3) of the DTX3L gene. This alteration results from a C to T substitution at nucleotide position 752, causing the proline (P) at amino acid position 251 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
