Abstract: On the basis of comparative mapping between cattle/sheep and human for milk trait quantitative trait loci (QTL) on BTA3/OAR1, annexin A9 (ANXA9) and solute carrier family 27 (fatty acid transporter), member 3 (SLC27A3) were selected as candidate genes for fat content (FC) in sheep milk. Two other genes in the same region, cingulin (CGN) and acid phosphatase 6, lysophosphatidic (ACP6), were also considered. DNA fragments of 1931 and 2790 bp corresponding to ANXA9 and SLC27A3 respectively were isolated, and 14 and 6 single nucleotide polymorphisms (SNPs) respectively were found in each gene. ANXA9, SLC27A3, CGN and ACP6 were localized to chromosome 1 between INRA006 and AE57 by linkage mapping using the International Mapping Flock. Across-family analyses of a daughter design comprising 13 sire families revealed significant sire and SLC27A3 genotype-nested-within-sire effects for FC. Within-family analyses indicated significant regression coefficients for FC in four of six heterozygous sires. These results could reflect the existence of a QTL for FC linked to SLC27A3 in sheep.
