Geroderma Osteodysplastica With Concomitant Transposition of Great Vessels: A Case Report and Literature Review.

Abstract

Geroderma Osteodysplastica (GO) is a rare autosomal recessive connective tissue disease characterized by wrinkled skin and osteoporosis, two distinct aging-related features. A loss of function mutation in GORAB results in the disease. Immediately after birth, a cyanotic female neonate was found to have transposition of great vessels (TGV) that was corrected with an uneventful surgical recovery. The patient was noted to have wrinkled skin and hyperlaxity in her joints. After a complete nutritional and metabolic panel, in addition to karyotyping, imaging, skin histopathology analysis, and genetic testing she was found to have GO. We found two novel compound heterozygous mutations in GORAB: p.Asp236∗ and pAsp236Ala. This is the first study that reports the concurrent incidence of GO with TGV. The patient was started on bisphosphonates, which led to a reduction in the occurrence of fractures. An early diagnosis of GO is warranted to prevent or reduce bone density loss due to osteoporosis via initiation of bisphosphonate treatment. Whole exome sequencing remains the gold standard for diagnosing GO and ruling out phenotypically similar disorders.
