Er mwyn cydnabod yr angen i godi ymwybyddiaeth o glefydau prin, rydym wedi ymuno â’r gadwyn oleuni fyd-eang, a bydd adeilad Llywodraeth Cymru ym Mharc Cathays wedi’i oleuo heno ‘ma #LightUpForRare.
To recognise the need to raise awareness of rare diseases, we have joined the global chain of lights and the Welsh Government’s Cathays Park building will be lit up this evening #LightUpForRare.
