This review compiled primary literature from 2007 to 2019 to evaluate the utility of exome/ genome sequencing in patients with congenital anomalies, developmental delay or intellectual disability (CA/DD/ID). After review of 7178 publications, 167 met criteria for evaluation including 36 with >20 patients. For the studies with larger  sample sizes, utility was evaluated following ES and/or GS (ES= 27; GS = 7; ES/GS = 2) with a range in sample size from 22-278.  Ninety-five percent of studies reported a change in clinical management including changes in medication, procedures, specialist referrals, redirection of care and clinical trial opportunities.  More than half of patients experienced a reported clinical impact related to a ES/GS diagnosis and more than half of studies with >20 patients identified an impact on family planning or reproductive decision-making. There was a paucity of data describing improved morbidity and mortality; however, there was sufficient, indirect evidence of the clinical and personal utility of exome/genome sequencing in patients with CA/DD/ID. The committee concluded that there is a need for a more formal framework to evaluate outcomes for ES/GS. This review will be used to guide the development of an evidence-based guideline.

Estimating cumulative point prevalence of rare disease: analysis of the Orphanet database.
Nguengang Wakap S, Lambert DM, Orly A, Rodwell C, Gueydan C, Lanneau V, Murphy D, Le Cam Y, Rath A.. Europ J Hum Genet. 2019;

Nguengang Wakap et al. analyzed epidemiological data in the Orphanet database to determine a cumulative point prevalence of rare disease. Analysis included information in database as of October 1, 2018. Based on all cases in the database, the authors estimate that RD affects at least 3.5-5.9% of the global population and approximately 72% of RD are reported to have a genetic etiology. This publication limits its calculations to only unique clinical disorders, therefore, removing the possibility of duplicate counting and overestimation.
