Objectives

Narrative objectives1

This multicenter, prospective observational (registry) study evaluates the clinical feasibility of rapid genomic diagnosis and the usefulness of a multidisciplinary family-support program for newborns with differences of sex development (DSD) in whom legal sex assignment is difficult. It also assesses the effectiveness of shared decision-making support for sex assignment, longitudinal changes in parental psychological status and family quality of life, and differences in outcomes according to the availability of multidisciplinary care, while establishing a nationwide registry of neonatal DSD.

Assessment

Primary outcomes

Diagnostic yield: the proportion of patients in whom rapid genomic testing identifies a pathogenic (P) or likely pathogenic (LP) variant and establishes a molecular genetic diagnosis, assessed during the study observation period.

Key secondary outcomes

1. Time to diagnosis: days from the first visit to the date the analysis result is reported to each site, and the corresponding age in days.
2. Time to legal sex assignment: days from the first visit to the date the sex field of the birth registration is submitted, and the corresponding age in days.
3. Distribution of DSD etiologies and distribution of the External Genitalia Score (EGS).
4. Proportion of cases with correction of the legally assigned sex at 1 and 5 years of age.
5. Quality of shared decision-making (SDM-Q-9).
6. Parental scores and longitudinal changes in psychological distress (K10), traumatic stress (IES-R), decision regret (DRS), perceived uncertainty (PPUS), and the concept of gender (HABS, GDS, GES, etc.).
7. Exploratory between-group comparison of the multidisciplinary-team sites and the collaborating sites.

Key inclusion criteria

1. Newborns with DSD under 14 days of age in whom the attending physician has deferred legal sex assignment, with an External Genitalia Score (EGS) of >=0.5 that is below the 10th percentile for boys by gestational age (10.5 at >=33 weeks, 9.0 at 28-32 weeks, 8.5 at <28 weeks).
2. Patients who began care at a participating site of this study.
3. Patients for whom written consent has been obtained from a parent (legally authorized representative).

Key exclusion criteria

1. Patients with a prenatally identified numerical sex-chromosome abnormality or similar finding.
2. Patients with a high likelihood of congenital adrenal hyperplasia, such as those with skin hyperpigmentation.
3. Patients judged to have a poor life prognosis due to serious comorbidities.
4. Any other patient judged unsuitable by the principal investigator.
