Genes affected

UBA6 (HGNC:25581): (ubiquitin like modifier activating enzyme 6) Modification of proteins with ubiquitin (UBB; MIM 191339) or ubiquitin-like proteins controls many signaling networks and requires a ubiquitin-activating enzyme (E1), a ubiquitin conjugating enzyme (E2), and a ubiquitin protein ligase (E3). UBE1L2 is an E1 enzyme that initiates the activation and conjugation of ubiquitin-like proteins (Jin et al., 2007 [PubMed 17597759]).[supplied by OMIM, Mar 2008]

The c.3044C>A (p.P1015H) alteration is located in exon 33 (coding exon 33) of the UBA6 gene. This alteration results from a C to A substitution at nucleotide position 3044, causing the proline (P) at amino acid position 1015 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
