This presentation provides an overview of genetics relevant to pediatric endocrine nursing practice. A brief genetic primer for nurses will be given followed by discussion of patient and clinician barriers to genetic literacy. Genetic competencies for nursing practice will be reviewed and application will be demonstrated through several pediatric endocrinecase presentations. At completion, participants will be able to incorporate concepts of genetic literacy and apply genetic ...

Background: Continuous glucose monitoring (CGM) devices are novel tools to measure the impact of dietary intake on glucose rhythms/metabolism in children. There is a significant gap in the literature on glycemic response in healthy, term infants and young children up to 2 years of age.Objective: To investigate glucose excursions in response to infant feeding, using CGM in healthy 6–12-month-old infants.<p class...

Background: POU1F1 encodes a pituitary-specific homeodomain transcription factor that is crucial for development and differentiation of anterior pituitary cell types. Mutations in this gene result in GH, TSH and prolactin (PRL) deficiencies.Objective and hypotheses: To describe a male newborn of a mother with known dominant p.R271W mutation in the POU1F1 gene.Methods: Case report with clinical follow up, endocrine investigations, n...

Background: Diabetes mellitus (DM) is a chronic metabolic disorder requiring daily care to prevent both acute and chronic complications. Intensive support to facilitate coping and self-care skills is advocated. Healthcare providers are challenged to manage the transition of adolescents from paediatric to adult diabetes services.Objective and hypotheses: While centres providing structured integrated paediatric and adult care seem optimal, many patients op...

Background: Chimerism is the phenomenon of two or more genetically distinct cell lines (originating from different zygotes) in the same individual. In situations when the sex of the fertilised eggs is disparate, it can lead to intersex phenotypes.Objective and hypotheses: We report a case of ovotesticular disorder of sexual development with chimerism resulting from a twin pregnancy (not involving assisted reproductive technologies).<p class="abstext"...

Background: Over the past 20 years there is growing evidence that onset of puberty and changes in body proportions occur at an earlier age, especially in girls. Several studies have suggested this trend is linked to increasing rates of overweight and obese children. However, data on delayed pubertal trends are scant.Objective and hypotheses: To characterize body proportions of children evaluated for pubertal disorders.Method: Retro...

Background: Mutations in the gene encoding the Chromodomain Helicase DNA-binding protein 7 (CHD7) are found in 60% of patients with CHARGE Syndrome (Coloboma, Heart Defects, Choanal Atresia, Retarded growth and development, Genital hypoplasia, Ear abnormalities and/or hearing problems) and in 6% of patients with Kallmann syndrome.Objectives and hypotheses: To describe a novel CHD7 mutation and its clinical presentation.<p class="abs...

Background: Polycystic ovarian syndrome (PCOS) is the most common endocrine disease among women of reproductive age with a prevalence of about 8% according to the Androgen Excess Society (AES) criteria. The pathophysiology of PCOS is not well understood and it is associated with a high prevalence of metabolic disorders. During puberty, irregular menses and acne are common, thus making the diagnosis of PCOS in adolescence challenging.Objective and hypothe...

Background: The hepatokine FGF21 signals through a dual receptor complex consisting of FGFR1c and the obligatory co-receptor β-Klotho to regulate glucose and lipid metabolism. Interestingly, female mice with Fgf21 transgenic overexpression are not only resistant to high-fat diet induced obesity but also present with hypogonadotropic hypogonadism (HH) and infertility. Loss-of-function (LOF) mutations in FGFR1 are a frequent cause of congenital HH (CHH). W...

Background: For young adults with type 1 diabetes, transition from a paediatric setting to an adult care setting is a vulnerable period with risks for gaps in care. These emerging adults need to develop skills for managing their diabetes yet it is often challenging to cover all anticipatory guidance topics related to type 1 diabetes. In the context of a structured transition clinic, we hypothesized that by leveraging teens’ facility with technology and marketing/design we...
