A Confirmatory Case of Severe Spondylocostal Dysostosis Caused by Biallelic Loss‐of‐Function of DMRT2

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Spondylocostal dysostosis (SCDO) is a rare genetic disorder characterized by abnormal development of the axial skeleton, resulting in malformations of the vertebrae and ribs that often impair lung development and lead to significant respiratory morbidity.

Clinically Irrelevant Terminal 16q21 Deletion Detected by NIPT Is Attributable to Inherited Fragility at FRA16B

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Genome‐wide non‐invasive prenatal testing (NIPT) is a powerful tool for prenatal detection of the common aneuploidies causing Down‐, Edwards‐, and Patau syndrome. Its genome‐wide reach also enables the detection of unbalanced structural chromosomal abnormalities.

An OGT Missense Variant With Impaired Enzyme Activity in a Child With Severe Developmental Delay and Hepatoblastoma

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT O‐GlcNAc transferase (OGT) and its antagonist O‐GlcNAcase (OGA) regulate protein O‐GlcNAcylation, a highly conserved post‐translational modification involved in metabolic sensing. Pathogenic variants in the OGT gene cause an X‐linked congenital disorder of glycosylation (OGT‐CDG) presenting developmental delay, hypotonia, intellectual ...

A Collaborative Approach to Pediatric Genetic Evaluation in the Era of Genomic Medicine

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT To address the increased demand for genetic services and shortage of medical geneticists (MG), a collaborative pilot program was developed with a two‐part approach to care: (1) Initial genetic counselor (GC) appointment with exome sequencing (ES) and (2) follow‐up MG evaluation.

The HRAS Variant c.175G>A (p.Ala59Thr) Causes a Predominantly Ectodermal Phenotype Lacking Classic Costello Syndrome Features

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Costello syndrome (CS) is a rare dominant HRAS RASopathy characterized by curly hair, cardiac abnormalities, craniofacial anomalies, and developmental delay. HRAS codon 58, 59, and 60 variants are associated with milder phenotypes. We describe a three‐generation family with a previously unreported heterozygous HRAS variant c.175G>A (p.Ala59Thr)
