Abstract
BACKGROUND Due to the COVID-19 pandemic, many genetics clinics across the country were prompted to integrate telephone visits and videoconferencing into their practice to promote the safety of patients and clinic staff members. Our study examined providers' perspectives on the utility and effectiveness of these telehealth-based clinic visits in response to the COVID-19 pandemic in Wisconsin. METHODS An anonymous Qualtrics survey was distributed via email in October 2020 to all members of the Wisconsin Genetic Systems Integration Hub and the Wisconsin Genetic Counselor Association. Current clinical genetic providers were eligible to participate in the survey. The survey assessed providers' experiences and perceptions toward utilizing telehealth in delivering clinical genetic services to their patients during the pandemic. RESULTS Forty-seven currently practicing clinical genetic counselors in Wisconsin either partially or fully completed the survey. Nearly all respondents somewhat (23%) or strongly (75%) wanted to incorporate telehealth in the future, primarily because of perceived improvements in clinic functioning. Patients with suboptimal telecommunications capacities were considered the most challenging aspect of telehealth, and better technology support was the most frequently cited strategy for addressing current telehealth limitations. CONCLUSION Clinical genetic counselors in Wisconsin generally reported positive experiences integrating telehealth into their patient care during the COVID-19 pandemic. Many counselors see telehealth as a way to increase access to genetic services and, with better technology support from their intuitions, would support utilizing telehealth in their clinical practice.

Abstract
Prenatal genetic screening should be an informed, autonomous patient choice. Extrinsic factors which influence patient decision-making threaten the ethical basis of prenatal genetic screening. Prior research in the area of medical decision-making has identified that labeling may have unanticipated effects on patient perceptions and decision-making processes. This Internet-administered study explored the impact of option labeling on the noninvasive prenatal screening (NIPS) selections of US adults. A total of 1,062 participants were recruited through Amazon Mechanical Turk (MTurk) and randomly assigned to one of three possible label sets reflecting provider-derived and industry-derived option labels used in prenatal screening. Multinomial logistic regression analysis showed option labeling had a statistically significant impact on the NIPS selections of study participants (p = .0288). Outcomes of the Satisfaction with Decision Scale (SWD) indicated option labels did not play a role in participant satisfaction with screening selection. The results of this study indicate a need for further evaluation of the impact NIPS option labeling has on patient screening decisions in real-world clinical interactions. Clinical providers and testing laboratories offering NIPS should give careful consideration to the option labels used with prenatal screening so as to minimize influence on patient screening selection and decision-making processes.

Abstract
The aim of this pilot qualitative study was to describe the experiences and beliefs of medical interpreters when working with genetic counselors and other genetic providers caring for Hmong patients who are not native English speakers. Specific goals were to identify interpreters' thoughts and perceptions on (a) their roles during sessions, (b) unique challenges in a genetics session, (c) knowledge genetics providers need when working with Hmong patients and interpreters, and (d) supports and training needed to effectively interpret in a genetics setting. Hmong medical interpreters from Wisconsin and Minnesota were invited by email to participate in the study. Six were interviewed by telephone. Participants had worked with a variety of providers including geneticists, genetic counselors, primary care physicians, and oncologists. Factors identified by Hmong interpreters that made interpretation of content difficult in clinical genetics sessions included: time constraints, technical terms, and unique cultural perspectives of Hmong patients. While all respondents felt their primary role was to interpret session content as close to verbatim as possible, there was notable variation in the description of their interpretation style and other perceived roles in the genetic counseling session. Cultural issues genetics providers could consider when working with Hmong patients and different style issues when working with Hmong interpreters are discussed. Ideas for future studies and suggestions to improve communication with Hmong patients are explored.

Abstract
Genetic counselors are trained to provide personalized genetic information and support to clients and their families. When requests for counseling comes from the counselor's own family member, should that counselor still provide service? There is a paucity of literature regarding genetic counselors counseling their own family members and no specific recommendations regarding how to reply to requests for genetic information from relatives. The purpose of this mixed methods study was to report genetic counselors' and genetic counseling students' perspectives and experiences providing genetic counseling to relatives. In the present study, 423 genetic counselors and genetic counseling students completed a 70-item web-based survey that explored genetic counselors' experiences counseling family members outside of a clinic setting. The majority (73%; n = 301/410) of respondents have been asked to provide genetic counseling. Over half (57%; n = 257/423) provided counseling, personalized genetic information or risk assessment to family members. Only a small fraction of respondents (11%; n = 45/420) responded that they received any formal training in their graduate education, or in any other capacity that addressed the issue of how genetic counselors should respond to genetic counseling requests made family members. Those who have were less likely to provide genetic counseling to a family member (p < 0.05). Respondents who provided genetic counseling to relatives were significantly more likely to think their colleagues would do the same. Those who never provided genetic counseling to relatives were more likely to think their colleagues would refer to an unrelated genetic counselor (p < 0.0001). We highlight how our results have clinical and professional implications and provide suggestions to generate discussion among genetic counselors on how they might respond to requests for counseling from family members.

Abstract
Progressive pseudorheumatoid dysplasia (PPRD) is a rare, autosomal-recessive condition characterized by mild spondyloepiphyseal dysplasia (SED) and severe, progressive, early-onset arthritis due to WISP3 mutations. SED, Stanescu type, is a vaguely delineated autosomal-dominant dysplasia of unknown genetic etiology. Here, we report three individuals from two unrelated families with radiological features similar to PPRD and SED, Stanescu type who share the same novel COL2A1 variant and were matched following discussion at an academic conference. In the first family, we performed whole-exome sequencing on three family members, two of whom have a PPRD-like phenotype, and identified a heterozygous variant (c.619G>A, p.Gly207Arg) in both affected individuals. Independently, targeted sequencing of the COL2A1 gene in an unrelated proband with a similar phenotype identified the same heterozygous variant. We suggest that the p.Gly207Arg variant causes a distinct type II collagenopathy with features of PPRD and SED, Stanescu type.

Abstract
This article describes the development of a tailored family-centered approach to genetic counseling following abnormal newborn screening (NBS) for cystic fibrosis (CF). A genetic counseling consortium reviewed research literature, selected theoretical frameworks, and incorporated counseling psychology micro skills. This innovative intervention integrated theories and empirically validated techniques. Pilot testing and parent feedback confirmed satisfaction with and feasibility of the approach designed to (a) minimize parents' distress, (b) facilitate parents' understanding, (c) increase parents' capacities to use genetic information, and (d) enhance parents' experiences with genetic counseling. Counselors engage in a highly interactive process of evaluating parents' needs and tailoring assessments and interventions that include a therapeutic environment, the family's emotional needs, parents' informational needs, and a follow-up plan. This promising new model is the first to establish a theory-driven, evidence-based standard for genetic counseling in the context of NBS for CF. Additional research will evaluate the model's efficacy in clinical practice.

Abstract
Transient kyphotic deformity arises in most infants with achondroplasia. In a minority, a fixed and angular kyphosis develops, which can cause serious neurologic sequelae later in life. We assessed a protocol for preventing development of such fixed kyphosis in a sequential, unselected series of 66 infants with achondroplasia. This study demonstrates the efficacy of early prohibition of unsupported sitting and, in those in whom such prohibition proves insufficient, use of bracing. When the proposed algorithm was followed, none of the infants had development of a progressive kyphotic deformity. On this basis, it appears that the secondary risks of angular kyphosis, previously estimated to be between 10 and 15% in individuals with achondroplasia, can be completely eliminated.

Abstract
We assessed the utility of radiographic findings as aids to the diagnosis of Down syndrome (DS) in stillborn infants. The iliac index may help to confirm the diagnosis of DS in stillborn infants in whom it is suspected clinically, but in whom it cannot be confirmed cytogenetically. It also can serve as a screening procedure to select stillborns in whom fluorescent in situ hybridization of fixed tissues should be completed. An iliac index of 59 degrees differentiates between control and affected stillborns with the highest accuracy, but false positives persist above 55 degrees, and false negatives are common below 64 degrees. We recommend that a conservative cutoff value of 55 degrees be used if the radiographic data serve as the principal means of diagnosing DS in stillborn infants. A cutoff value of 64 degrees may be appropriate if the radiographic data are used to screen stillborn infants for fluorescent in situ hybridization studies.

Abstract
Achondroplasia, the most common skeletal dysplasia, is characterized by delayed and aberrant motoric development in childhood. Delays and aberrancy are secondary to the anatomical differences inherent in people with achondroplasia. We present a photographic essay documenting biophysical differences, aberrant pre-orthograde movement strategies, and selected adaptive techniques. A parental questionnaire assessed the presence of, predominance, and ages at which various types of pre-orthograde locomotion were observed. Fine and gross motor skills were assessed contemporaneously by use of the Denver Developmental Screening Test in 93 children with achondroplasia and were found to be more delayed than previously reported. Physicians, therapists, early-childhood educators, and parents should recognize that aberrant does not mean maladaptive and that different development is not defective development.

Abstract
Achondroplasia, the most common heritable skeletal dysplasia, may result in abnormality at the craniocervical junction, which is a potentially lethal problem in a subset of young infants with this disorder. We evaluated and followed an unbiased and unselected consecutive series of infants with achondroplasia, to better document the occurrence, frequency, and clinical presentation of craniocervical abnormalities. Of 53 prospectively ascertained infants, 5 were judged to have sufficient craniocervical junction compression to require surgical decompression. Intraoperative observation always showed marked abnormality of the cervical spinal cord, and all operated-on children showed marked improvement of neurological function. The most frequent clinical abnormalities within this subset were those expected for high cervical myelopathy. The best predictors of need for suboccipital decompression included lower-limb hyperreflexia or clonus, on examination; central hypopnea demonstrated by polysomnography; and foramen magnum measures below the means for children with achondroplasia. Infants with achondroplasia are at risk for potentially lethal sequelae of craniocervical junction abnormalities; selective intervention can be life and health saving, but individuals at high risk will be identified only if all affected infants undergo comprehensive assessment in infancy.

Abstract
Although stillbirth is a common event, few programs have previously been established for the comprehensive etiologic investigation of intrauterine death. Fewer still have been prospective, unbiased in ascertainment, and consistent in protocol utilization. The Wisconsin Stillbirth Service Program was established in 1983 as a unique model for the investigation of the causes of stillbirth. This community-based, University-supported model for health care delivery is here described. Through it more than a thousand infants have been etiologically investigated. We demonstrate that a community-based program of stillbirth assessment can succeed, that compliance with recommended protocols is high and that a specific primary cause of fetal death can be demonstrated in about 40% of referrals. A majority of the established causes of intrauterine death are fetal etiologies. Furthermore, it appears that there are no substantial referral biases. Lack of such biases, together with the prospective, protocol driven nature of the program provides a unique population upon which to base estimates of the frequency of various etiologic diagnoses and classes and categories of cause.

Abstract
The Wisconsin Stillbirth Service Program has provided a mechanism for the collection and analysis of unbiased and representative information concerning stillborn infants. Generated diagnoses and diagnostic categories within the first 1,000 referrals (including 789 stillbirths) is summarized here. Among all referred stillborns, 24.5% were found to have an identifiable intrinsic fetal cause of death. Specific diagnoses were extraordinarily heterogeneous, with about 85 different processes identified with this group. No single diagnosis was found in more than 1 1/2% of the evaluated stillborns. Distribution by classes of fetal causes (as a percent of all fetal causes in stillborns) included malformation syndromes in 44%, single malformations and defined sequences in 34%, disruptions in 10%, and dysplasias in 3%. The heterogeneity of syndromic causes is illustrated, examples of previously undescribed syndromic processes provided and the problems experienced in generating specific diagnoses discussed. Specific single malformations, sequences, disruptions, and dysplasias are also tabulated and illustrated. Distribution by etiologic categories (as a percent of all fetal causes in stillborns) included defined sporadic conditions in 29%, cytogenetic aberration in 25%, presumed multifactorial processes in 12%, Mendelian disorders in 5%, and environmental events in less than 4%. A fourth of all fetal causes could not be sufficiently defined to allow for certainty in assigning a specific etiologic category. The materials summarized provide reference data regarding the frequency of classes and categories of fetal diagnoses generated from an unbiased and non-selected series of stillborns.

Abstract
The Wisconsin Stillbirth Service Project (WiSSP) is a community-based program for the investigation of the cause of fetal death. From its inception in 1983 through July 1988, 629 referrals were made to WiSSP. All referrals were assessed for the presence of disruptional characteristics, and 23 were found to have major or primary disruptive effects. Most of these were either early amnion disruption/limb-body wall disruption (treated as a single group, since analysis suggests a continuum of clinical characteristics) and twin-twin disruptions. Therefore, disruptions accounted for 3.6% of all referrals (including liveborn and miscarriage referrals) to WiSSP. When only stillborn fetuses are considered, approximately 2.4% appear to have died because of disruptions. This makes disruptions one of the most frequent, identifiable causes of late intrauterine death. We estimate that 0.6-1.4% of all stillborn fetuses die because of early amnion disruption/limb-body wall disruption which, when taken with previous estimates of the frequency of such problems in early miscarriages and liveborn infants, suggests that these disruptions result in a 95% prenatal mortality rate. We suggest a unified model of likely pathogenetic mechanisms which may help explain the continuum of multisystem involvement seen in those with early amnion disruption/limb body wall disruption. In addition, 3 patients with atypical disruptions are reviewed who exemplify the difficulty and importance of differentiating disruptional and malformational processes.

Abstract
We review six families in which recurrence of achondroplasia, inexplicable through autosomal dominant inheritance, has occurred. The clinical and radiographic characteristics of affected individuals in these families are identical to those usually seen in achondroplasia. Family histories and parental characteristics likewise seemed not to set this group apart from others with achondroplasia. While various mechanisms for these occurrences of achondroplasia in family members related through unaffected relatives can be postulated, the hypothesis that these recurrences were simply the result of two independent chance events cannot, at least for the moment, be excluded.
