Abstract: Provided herein a method for enhanced assessment of breast cancer in a subject including identification of circulating breast cancer cells in a biological sample and single-cell, whole-genome sequencing of the identified circulating breast cancer cells. Optionally, cell-free tumor DNA is further assessed from the same biological sample or a parallel sample. Also provided are methods of treating a subject with breast cancer using the enhanced assessment to select one or more anti-cancer agents for administering to the subject.

Abstract: The methods and compositions of the invention find use in the clinical diagnosis of primary immunodeficiencies, particularly Wiskott-Aldrich related syndromes. The compositions of the invention include isolated nucleic acid molecules and oligonucleotide pairs suitable for use in amplifying regions of the Wiskott-Aldrich syndrome protein gene and in determining the nucleotide sequence of the Wiskott-Aldrich syndrome protein gene in a patient. The invention facilitates efficient, cost-effective amplification of one or more regions of the Wiskott-Aldrich syndrome protein gene. The nucleotide sequence of amplified DNA comprising one or more regions of the Wiskott-Aldrich Syndrome Protein gene can be determined using the methods and compositions of the invention. Knowledge of the patient's nucleotide sequence in the Wiskott-Aldrich Syndrome Protein gene allows diagnosis of the patient's primary immunodeficiency.

Abstract: The present invention is related to diagnostic arrays comprising primers for various regions of candidate genes involved in hearing loss, specifically pediatric hearing loss. The invention further is directed to methods for diagnosing a cause or risk factor for hearing loss. In some embodiments, these methods include obtaining a sample from a patient; screening the sample for the presence or absence of alleles of at least 5 loci associated with a risk for hearing loss to obtain a result of the screening; and making a diagnosis based upon the result. The present invention is also directed to the amplification of genetic sequence from multiple or single exons for use in the screening of samples.
