As more therapeutics for genetic conditions become available, the need for timely and equitable genetic diagnosis has become urgent. Using clinical cases, we consider the health system-, provider-, and patient-level factors that contribute to the delayed diagnosis of genetic conditions in pediatric patients from minority populations, leading to health disparities between racial groups. We then provide suggestions to address these factors, with the aim of improving minority health and access to genetic care for all children.

BackgroundTARP syndrome, characterized by talipes equinovarus, atrial septal defect, Robin sequence, and persistent left superior vena cava, is an X‐linked recessive condition caused by deleterious variants in RBM10. Vitelline vascular remnants (VVR) are a rare vitelline duct anomaly with approximately 26 cases previously reported. There are no previously reported cases of VVRs in patients with TARP syndrome.CaseWe present a male neonate diagnosed with TARP syndrome via trio whole exome sequencing who had classic features of this syndrome, although his course was additionally complicated by feeding intolerance with multiple episodes of abdominal distension. Serial imaging and contrast studies of the upper GI tract and small bowel demonstrated small bowel obstruction of unclear etiology. Given the poor prognosis associated with this condition, life‐sustaining measures were withdrawn, and he passed away at 38 days of age. On autopsy, a VVR was unexpectedly identified with proximal bowel dilation, explaining his feeding intolerance.ConclusionsWe highlight the importance of full post‐mortem examination in understanding the complete spectrum of manifestations of genetic syndromes and provide a review of the literature.
