The invention provides an SNP locus related to growth characteristics of patinopecten yessoensis. The locus is the 1054 site of IGFBP (Insulin Like Growth Factor Binding Proteins) genes of which the nucleotide sequence is shown as SEQ ID NO:2 and has the base of A or G. The invention also provides a probe for detecting the SNP locus and a parting primer. The transcription sequence of the IGFBP genes in the patinopecten yessoensis is subjected to sequencing and Clustal comparison, and three SNP loci are screened. The site polymorphism is detected in the patinopecten yessoensis group by using a high resolution melting curve technology, and correlation between the site genotype frequency and the growth characteristics of patinopecten yessoensis is analyzed. The locus C.1054A>G is obviously related to important growth characteristics such as the height, shell length, weight, soft weight and adductor muscle weight of the patinopecten yessoensis, the growth characteristics of the AG type individuals are obviously lower than those of AA and GG type individuals (P is less than 0.05), and the characteristic value of the GG type is the highest. Therefore, individuals of which the genotype is GG on the locus can be preferentially selected during production and are used as parents for performing high-yield patinopecten yessoensis breeding or performing large-scale breeding.

The invention relates to the field of medical science, and provides a biomarker for hepatocellular carcinoma related detection, particularly a biomarker for detecting HBV related hepatocellular carcinoma. The biomarker comprises an insulin-like growth factor binding protein 7 (IGFBP7) and an alpha fetoprotein (AFP). A method for detecting hepatocellular carcinoma, based on the biomarker namely the IGFBP7 and the AFP, comprises a step of carrying out judgement by measuring a marker IGFBP7 gene promotor methylation level and detecting the sensitivity of the marker AFP for being combined with serum IGFBP7 gene promoter methylation. According to biomarker, the AFP is combined with the IGFBP7 gene promoter methylation, so that the traditional detection of single indexes is changed, and the efficiency of HCC diagnosis is increased.
