Genes affected

UBE2NL (HGNC:31710): (ubiquitin conjugating enzyme E2 N like (gene/pseudogene)) This gene is intronless and encodes a member of the ubiquitin-conjugating enzyme family. The protein product is 91% identical to ubiquitin-conjugating enzyme E2N, a multi-exon gene product. This locus represents a polymorphic pseudogene, where some individuals contain an allele that can encode a full-length protein, while others have a non-functional allele containing a premature stop codon (reference SNP rs237520) that truncates the coding sequence.

Collection Method: clinical testing

The c.235C>T (p.P79S) alteration is located in exon 1 (coding exon 1) of the UBE2NL gene. This alteration results from a C to T substitution at nucleotide position 235, causing the proline (P) at amino acid position 79 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
