Protein sy'n cael ei godio yn y corff dynol gan y genyn UXS1 yw UXS1 a elwir hefyd yn UDP-glucuronic acid decarboxylase 1 ac UDP-glucuronate decarboxylase 1 (Saesneg). Segment o DNA yw'r genyn, sy'n amgodio ffwythiant arbennig. Mae'r genyn yma wedi ei leoli ar yr edefyn ôl o gromosom dynol 2, band 2q12.2.[2]
Yn aml mae gan enynnau lawer o gyfystyron. Mae hyn oherwydd eu bod yn aml yn cael eu darganfod gan nifer o bobl mewn cyd-destunau gwahanol heb wybod mai'r un genynnau oeddyn nhw. Hefyd mae gan wahanol gymunedau gwyddonol safonau gwahanol ar gyfer enwi genynnau. Dyma restr o gyfystyron ar gyfer y genyn UXS1.
