SAMPLE RETRIEVAL AND GENETIC ANALYSIS THEREOF
Retrieval of one or more samples from a pediatric subject for genetic analysis of the subject's nucleic acid is often invasive and inconvenient. Methods for analyzing nucleic acid include non-invasive and/or convenient methods of sample retrieval such as the retrieval of one or more samples for genetic analysis from a patient that may have an infection in conjunction with testing for the infection. In one aspect, the infection is strep throat. Methods for analyzing nucleic acid may also include the retrieval of a sample from a placenta that has been delivered during birth of a child. In one aspect, the sample is cord blood and in another aspect the sample is chorion tissue. Methods for analyzing nucleic acid include conducting a genetic analysis on the retrieved sample by exposing a nucleic acid to a plurality of MIPs and subsequently sequencing and aligning and assembling the reads generated therefrom.
1 . A method for analyzing nucleic acid in a subject, the method comprising:
retrieving a sample from a patient using a sample retrieval device;
eluting the sample from the sample retrieval device;
separating the sample into at least a first portion and a second portion;
testing for the infection in the first portion; and
conducting a genetic analysis on the second portion.
2 . The method of claim 1 , wherein the infection is Group A Beta Hemolytic Streptococcus.
3 . The method of claim 1 , wherein the sample retrieval device is a swab.
4 . The method of claim 3 , wherein the retrieving step comprises using the swab to obtain the sample from the patient's throat.
5 . The method of claim 1 , wherein the conducting step comprises exposing a nucleic acid to a plurality of molecular inversion probes (MIPs), each MIP comprising two targeting arms designed to hybridize upstream and downstream of a target in a genome.
6 . The method of claim 1 , wherein the genetic analysis comprises determining the genotype of the subject.
7 . The method of claim 1 , wherein the genetic analysis comprises screening for one or more genetic diseases.
8 . A method for analyzing nucleic acid of a subject comprising:
retrieving a sample from a placenta that has been delivered during birth of a child, wherein the sample contains nucleic acid of the child; and
conducting a genetic analysis on the sample comprising exposing a nucleic acid to a plurality of molecular inversion probes (MIPs), each MIP comprising two targeting arms designed to hybridize upstream and downstream of a target in a genome.
9 . The method of claim 8 , wherein the sample is cord blood.
10 . The method of claim 8 , wherein the sample is chorion tissue.
11 . A method for analyzing nucleic acid of a subject comprising:
retrieving a sample from a patient using a swab;
eluting the sample from the swab; and
conducting a genetic analysis on the sample.
12 . The method of claim 11 , wherein the retrieving step comprises using the swab to obtain the sample from the patient's throat.
13 . The method of claim 11 , wherein the conducting step comprises exposing a nucleic acid to a plurality of molecular inversion probes (MIPs), each MIP comprising two targeting arms designed to hybridize upstream and downstream of a target in a genome.
14 . The method of claim 11 , wherein the genetic analysis comprises determining the genotype of the subject.
15 . The method of claim 11 , wherein the genetic analysis comprises screening for one or more genetic diseases.
