OBJECTIVE To develop a fetal sex determination method based on maternal plasma sequencing (MPS), assess its performance and potential use in X-linked disorder counseling. METHODS 900 cases of MPS data from a previous study were reviewed, in which 100 and 800 cases were used as training and validation set, respectively. The percentage of uniquely mapped sequencing reads on Y chromosome was cal...
In many farm animal species, the preference of a specific sex is obvious mainly due to commercial implications; so for comprehensive and efficient results in the livestock management plans specially breedingand selection programs, it is necessary to include acost-effective and reliable strategy for early determination of fetal sex. Several invasive and non-invasive approaches have been establis...
the first step in the prenatal diagnosis of x-linked genetic disorders is determining fetus gender. current invasive methods to obtain the dna source of the fetus instead of its miscarriage risk, has harmful stress for high risk pregnancies. cell free fetal dna (cffdna) circulating in the maternal blood, has now become a useful source of noninvasive prenatal diagnosis. considering limitation of...
SRY Abstract Introduction: Prenatal diagnosis is testing for detection of diseases or conditions in a fetus or embryo before it is born. Most of prenatal diagnostic (PD) techniques are invasive and done in late stages of pregnancy. Using fetal DNA in maternal blood for fetal sex determination in early pregnancy might help in management of X-linked genetic diseases. This study aimed to investiga...
OBJECTIVE To examine the performance of a mass spectrometry-based detection platform using three Y-chromosome sequences for fetal sex determination from circulating cell-free fetal DNA (ccffDNA) in maternal blood in the first trimester of pregnancy. METHODS We extracted ccffDNA for the determination of fetal sex from stored maternal plasma obtained at 11 to 13 weeks' gestation from singleton ...
Background and purpose: In humans, SRY (sex-determining region of the Y chromosome) is the major gene for the sex determination which is found in normal XY males and rarely in XX males, and it is absent from normal XX females and from many XY females. There are several methods which can indicate a male genotype by amplification of SRY gene. The aim of this study was identification of the SRY ge...
Aim: Determination of fetal gender by palpating the intensity maternal pulse on right and left 5th finger, based Ayurvedic principle that there is a ‘nadi’ (a pathway or channel in human body) connecting pregnancy finger. Methods: 130 pregnant women from Obstetrics Pathology Department-UCK, Gdansk, Poland were included study. Twin pregnancies excluded. The finger was palpated followed palpation...
