The First Fetal Case of Shwachman-Diamond Syndrome Mimicking Vascular Growth Restriction.
Shwachman-Diamond Syndrome (SDS) is a rare autosomal recessive genetic condition with 90% of cases associated with biallelic pathogenic variants in the Shwachman-Bodian-Diamond Syndrome (SBDS) gene on chromosome 7q.11.21. SDS belongs to ribosomopathies since SBDS gene encodes a protein involved in ribosomal maturation. Its phenotypic postnatal hallmark features include growth delay, bone marrow failure, exocrine pancreatic insufficiency, and skeletal abnormalities. We report a first fetal case of Shwachman-Diamond syndrome and extend its phenotype before birth. The clinical features mimicked vascular growth restriction with FGR and shortened long bones, associated with abnormal Doppler indices. Non-restricted fetal autopsy after termination of pregnancy allowed deep phenotyping disclosing the features of fetal skeletal dysplasia. Post-fetopathological trio exome sequencing identified biallelic pathogenic variants in the SBDS gene. Genotype-phenotype correlations confirmed the diagnosis and enabled an adequate genetic counseling of the parents. Our case is another example of the positive impact of fetal autopsy coupled with post-fetopathological genomic studies, even in the cases that were hitherto classified as maternal or fetal vascular malperfusion.
期刊介绍:
The Journal covers the spectrum of disorders of early development (including embryology, placentology, and teratology), gestational and perinatal diseases, and all diseases of childhood. Studies may be in any field of experimental, anatomic, or clinical pathology, including molecular pathology. Case reports are published only if they provide new insights into disease mechanisms or new information.
