Hello dear Warm welcome to Healthcaremagic.com I have evaluated your query in details . * Celiac disease is hereditary . * The 1st degree relative ( parent , child , sibling ) has risk of 1 : 10 for development of celiac disease . * So evaluation for HLA DQ A1 and HLA DQB1 genes are required . Wishing you fine recovery . Feel free to ask any further queries . Regards .
