Pathogenic variants in TRAF7 are often de novo and features of individuals harboring these variants are characterized by neurodevelopmental delay, ptosis, cardiac defects, limb anomalies, and dysmorphic features. We present a familial case in two African American patients with a novel, likely pathogenic c.1936G>A variant in TRAF7. Patient 1 is a 31-year-old female with a patent ductus arteriosus (PDA), intellectual disability, ptosis, and other dysmorphic features. She was identified to harbor this likely pathogenic variant in a mosaic (33.89%) state in leukocytes. Her son, Patient 2, is a 10-month-old male with a PDA, atrial septal defect, ptosis, developmental delay, history of feeding difficulties, congenital maxillary frenulum, and malrotation of the intestine. He has the same variant in a non-mosaic state. These cases demonstrate the variable expressivity observed with variants in TRAF7 within the same family and expand upon current understanding of mosaic TRAF7 variants. They also provide phenotypic data on genetic variation in individuals with African American ancestry, a population who has been underrepresented in the literature and may be less frequently referred to genetic specialists.
