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.136T>G (p.S46A) alteration is located in exon 1 (coding exon 1) of the UBE2NL gene. This alteration results from a T to G substitution at nucleotide position 136, causing the serine (S) at amino acid position 46 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
