Gweld/Golygu Bod dynol

Protein sy'n cael ei godio yn y corff dynol gan y genyn C4A yw C4A a elwir hefyd yn Complement C4A (Rodgers blood group) (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 6, band 6p21.33.^[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 C4A.
