Gweld/Golygu Bod dynol

Protein sy'n cael ei godio yn y corff dynol gan y genyn FXN yw FXN a elwir hefyd yn Frataxin, mitochondrial a Frataxin (Saesneg). Segment o DNA yw'r genyn, sy'n amgodio ffwythiant arbennig. Mae'r genyn yma wedi ei leoli ar yr edefyn blaen o gromosom dynol 9, band 9q21.11.^[2]

Cyfystyron

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 FXN.
