Investigation of the Relationship Between Leptin Gene and Some Yield Traits in Sea Bream Sparus aurata by SNP Markers

Summary
<p>The genetic variations in a partial region of the <em>LEP</em> gene and its associations with growth traits were studied using DNA sequencing in gilthead sea bream (<em>Sparus aurata</em>) individuals. We identified 7 novel SNPs (g.4062183A>C, g.4062177G>A, g.4062092A>G, g.4062030G>A, g.4061965G>T, g.4061776T>A and g.4061756G>A) in the <em>LEP</em> gene in <em>Sparus aurata</em>. The genotypes of the g.4062092A>G locus nonsynonymous mutation in asparagine to aspartic acid in <em>Sparus aurata</em> 2nd ekzon of the <em>LEP</em> gene were found to be significantly associated with total weight, fillet weight, total length, standard length, head length, pectanal1 length, pectanal2 length, pectD length and body width (P<0.05). It is suggested that g.4062092A>G should be used as a potential marker to improve the accuracy of selection in gilthead sea bream cultured populations.</p>
