In total, 54 variants were found in ABCF1, 13 in HSPA1A, 16 in RXRB, 78 in TAP1, and 88 in TAP2. Whether these differences are due to the different composition of both sets in terms of individual characteristics of participants (the present set contained only females while the NCMG set is composed of both genders) or due to the disease etiology (breast cancer patients versus healthy population) remains to be elucidated. The gene discussed is ABCF1; the disease is breast carcinoma.
