Genes affected
SLX1A (HGNC:20922): (SLX1 homolog A, structure-specific endonuclease subunit) This gene encodes a protein that is an important regulator of genome stability. The protein represents the catalytic subunit of the SLX1-SLX4 structure-specific endonuclease, which can resolve DNA secondary structures that are formed during repair and recombination processes. Two identical copies of this gene are located on the p arm of chromosome 16 due to a segmental duplication; this record represents the more centromeric copy. Alternative splicing results in multiple transcript variants. Read-through transcription also occurs between this gene and the downstream SULT1A3 (sulfotransferase family, cytosolic, 1A, phenol-preferring, member 3) gene. [provided by RefSeq, Nov 2010]
SLX1A-SULT1A3 (HGNC:44437): (SLX1A-SULT1A3 readthrough (NMD candidate)) This locus represents naturally occurring read-through transcription between the neighboring SLX1A (SLX1 structure-specific endonuclease subunit homolog A) and SULT1A3 (sulfotransferase family, cytosolic, 1A, phenol-preferring, member 3) genes on the short arm of chromosome 16. A duplicate read-through locus also exists between the SLX1B and SULT1A4 genes located approximately 730 kb upstream on the same chromosome. The read-through transcript is a candidate for nonsense-mediated mRNA decay (NMD), and is thus unlikely to produce a protein product. [provided by RefSeq, Feb 2017]
