  • Patent number: 11840726
    Abstract: The present technology relates to methods for excluding Lynch syndrome as a possible diagnosis in patients suffering from colorectal cancers or endometrial cancers. These methods are based on detecting the methylation status of the MLH1 promoter ‘C’ region in colorectal and endometrial cancer patients using an improved and highly sensitive methylation-specific multiplex ligation-dependent probe amplification (MS-MLPA) assay.

  • Publication number: 20230265510
    Abstract: Methods for determining the presence or absence of expansion of CGG repeat sequence in the FMR1 gene presence or absence of expansion of CCG repeat sequence in the FMR2 gene are provided. The methods are useful in identifying an individual with normal/intermediate, versus premutation or full mutation allele of FMR1 gene and FMR2 gene due to the expansion of CGG repeats and CCG repeats in the 5?-untranslated region respectively. The methods are also useful for screening newborns for fragile X syndrome or for screening women to determine heterozygosity status with full premutation of the CCG repeat tract. The methods are also useful in estimating the premutation and full mutation carrier frequency and estimating the prevalence of FXTAS AND FXPOI in a population. The methods are simple, rapid and require small amount of sample.

  • Publication number: 20210324468
    Abstract: The present technology relates to methods for determining whether a patient having thyroid nodules with indeterminate cytology will benefit from diagnostic surgery, e.g., lobectomy. These methods are based on screening a patient's thyroid nodules and detecting alterations in target nucleic acid sequences corresponding to a specific set of thyroid cancer-related genes. Kits for use in practicing the methods are also provided.

  • Publication number: 20210130896
    Abstract: The present invention relates to methods for amplifying various regions of the cystic fibrosis transmembrane regulator (CFTR) gene. Methods are provided for amplifying one or all 27 exons of the CFTR gene and a portion of the CFTR promoter region in a single tube. The method can identify the presence or absence of CF deletions or insertions in a sample and assist in the diagnosis of a genetic predisposition to cystic fibrosis.
