Carrier Screening For Women Undergoing Elective Oocyte Cryopreservation (Eoc): A Look At Practice Among Reproductive Endocrinologists At An Academic Fertility Clinic, Melissa Manuelli

Human Genetics Theses

Elective oocyte cryopreservation (EOC) is a process involving freezing and banking oocytes with the intention to be used in the future for pregnancy. Cryopreserving oocytes allows women to enhance their reproductive autonomy by reducing the effects of age-relatedfertility decline. Similarly, expanded carrier screening (ECS) completed prior to conception allows women to consider their full range of reproductive options including in-vitro fertilization (IVF) with preimplantation genetic testing (PGT), use of donor gametes, and prenatal testing and diagnosis. In this retrospective chart review, we examine carrier screening practices for 106 EOC patients, and an age-matched control group of 106 IVF patients who …

The Impact Of A Lynch Syndrome Diagnosis By Population Genomic Screening On Family Communication, Medical Management, And Lifestyle Changes, Reem Ibrahim Bux, Brooke Nicole Delehoy

Human Genetics Theses

The purpose of population genomic screening programs is to help in prevention and treatment of conditions that takes into account an individual’s unique genetics, environmental, and lifestyle factors. Through this “genome-first” approach, individuals at increased lifetime risk for certain conditions are identified, allowing them and their relatives to qualify for preventative medical care and surveillance (Schwartz et al., 2018). An example institution that utilizes this approach is Geisinger’s MyCode Community Initiative, where their goal is to “make healthcare better” through research and its application to patient care (MyCode Community Health Initiative, n.d.). MyCode reports back medically actionable results for conditions …

Currently practicing genetic counselors were surveyed about their views of whether specific traits found to be valued in leaders in nursing were important in their bosses, institutional leaders, and genetic counseling professional society leaders. Likert scale responses were analyzed using descriptive and inferential statistics; qualitative …


An Investigation Into The Reasons Behind Quality Of Life Perception In Individuals With Hnpp As Compared To Individuals With Cmt1a, Caitlin Walsh, Sophia Rodriguez May 2020

An Investigation Into The Reasons Behind Quality Of Life Perception In Individuals With Hnpp As Compared To Individuals With Cmt1a, Caitlin Walsh, Sophia Rodriguez

Human Genetics Theses

Hereditary neuropathy with liability to pressure palsies (HNPP) and Charcot-Marie- Tooth Disease type 1A (CMT1A) are autosomal dominant hereditary neuropathies caused by different mutations in the PMP22 gene. The chronic features of CMT1A and HNPP are almost identical, leaving electrodiagnostic testing to assess nerve conduction as the vital distinguisher between these two diagnoses. Differing onset, duration and recovery, as well as genetic testing, can also help distinguish the diagnosis. Patients with CMT1A often have chronic and progressively worsening symptoms, whereas patients with HNPP experience transient, acute symptoms that may or may not be associated with pain and with possible milder …


Post Mortem Genetic Testing In Sudden Unexpected Death In Epilepsy [Sudep]: A Pilot Story, Yu An, Alejandra M. Cantú Villarreal May 2020

Post Mortem Genetic Testing In Sudden Unexpected Death In Epilepsy [Sudep]: A Pilot Story, Yu An, Alejandra M. Cantú Villarreal

Human Genetics Theses

Sudden Unexpected Death in Epilepsy [SUDEP] is one of the major causes of death within the world population that has epilepsy (Partemi, et al., 2014). There is no clear consensus on the underlying mechanism and are theorized to be heterogeneous in nature (Nashef et al., 2012). Some of these mechanisms are cardiac arrhythmias, and dysfunctions in either the respiratory or brainstem arousal systems (Ruthirago et al., 2018). Postmortem testing could provide further understanding of SUDEP and could be used as an asset to medical examiners. In this study we seek to evaluate the utility of postmortem genetic testing as part …

Exploration Of Patient Attitudes Toward Receiving Incidental Diagnoses Of Lysosomal Storage Disorders Through Expanded Carrier Screening, Ally Abbott, Xindi Song

Human Genetics Theses

The increased prevalence of expanded carrier screening (ECS) has made it possible for individuals to receive incidental diagnoses of genetic conditions through prenatal or preconception screening that was originally intended to assess risk for genetic conditions in future offspring. The inclusion of genetic conditions with variable expressivity and late-onset phenotypes, such as certain lysosomal storage disorders, have increased the likelihood that this type of screening will result in an incidental diagnosis. Four participants from the lysosomal storage disorders program at NYU Langone Health were interviewed to elicit their psychological reaction to incidental diagnoses of Gaucher Disease Type 1, Fabry Disease …

Descriptive Analysis Of The Testing Outcome Populations Of A Highly Facilitated Cascade Genetic Testing Framework For Cancer Predisposition, Samantha R. Anderson

Human Genetics Theses

This research analyzes the demographic determinants of testing uptake in a highly facilitated cascade testing protocol pilot effort for families with inherited cancer-predisposing mutations. The program provided no-cost genetic testing to the family members of mutation carriers using direct contact, telephone genetic counseling, and mailed saliva kits. This facilitated intervention resulted in high uptake of testing for second degree relatives and reduced sex-based risk disclosure. Uptake rates were highest among females and older individuals. Young Caucasian males were most likely to decline testing. Contact was limited for non-Caucasian and international individuals with low English-language proficiency, resulting in lower uptake rates …


Genetic Counseling Students’ Attitudes Towards Psychiatric Illness, Rebecca Haegedorn, Patricia Thompson May 2019

Genetic Counseling Students’ Attitudes Towards Psychiatric Illness, Rebecca Haegedorn, Patricia Thompson

Human Genetics Theses

Mental illness is very common, with some estimates that up to 50% of the population will experience a diagnosable mental illness in their lifetime (Moffitt et al., 2010). Because of this, genetic counselors are likely to come across mental illness in patients throughout their careers. Stigma towards mental illness is a well-documented phenomenon, both in society and in the healthcare field (Mann & Himelein, 2004; Nordt, Rӧssler, & Lauber, 2006; Reavley & Jorm, 2011). It is possible that estimates of negative attitudes and stigma collected from genetic counseling trainees in past studies are underestimates, as they have relied on measures …

Should Genetic Information Be Used To Determine Special Education Eligibility And Other Educational Services?, Nicholas Staropoli

Human Genetics Theses

Clinically, genetic testing is recommended for all children who have been diagnosed with autism. However, genetic testing is no longer being used solely as a medical tool and social uses of this are being introduced, such as in educational settings. But using this information to determine who is eligible for educational services introduces a litany of ethical, legal and social issues. We recruited 400 parents to complete an online survey to gauge their opinions on using genetic information to determine special education eligibility and other school services for children with autism. Overall, the 77.3% of parents were in support of …

Attitudes Of Healthcare Professionals Towards The Utilization Of Genetics Professionals Following The Diagnosis Of Autism Spectrum Disorder, Sydney Alexandra Lau, Tova Lejtman Wagner

Human Genetics Theses

Autism spectrum disorder (ASD) is a group of neurodevelopmental disorders characterized by social communication deficits and repetitive behaviors. A diagnosis of ASD can be made by various healthcare professionals, including developmental pediatricians, child neurologists, child psychiatrists, and child psychologists. As there is a significant genetic component to ASD, many professional organizations recommend that individuals diagnosed with ASD undergo some form of genetic testing; notably, psychological organizations do not make any such recommendation. Nevertheless, current literature has shown that most patients are not referred to genetics. This study compared the utilization of genetic professionals by physicians and psychologists. It was hypothesized …


Sun Exposure As A Risk Factor For Precipitating Vision Loss For Individuals With Lhon Mitochondrial Variants, Michelle Kowanda May 2019

Sun Exposure As A Risk Factor For Precipitating Vision Loss For Individuals With Lhon Mitochondrial Variants, Michelle Kowanda

Human Genetics Theses

Vision loss in Leber hereditary optic neuropathy (LHON, OMIM# 535000) is caused by pathogenic LHON associated mitochondrial DNA (mtDNA) variants that are often considered to be triggered by a second environmental stress (genotype-­ environmental double hit). A few studies have demonstrated associations between the onset of LHON vision loss and specific environmental stresses such as tobacco or alcohol use. Other plausible triggers, such as UV exposure through sunlight, has not yet been studied. The purpose of this study was to survey LHON patients’ lifestyle and habits to investigate the risk of light exposure on this population, including the correlation of …
