RESUMO
Coexistence of TGM1 and FLG mutations in a newborn with congenital ichthyosis is not well described in the literature. Early genetic testing and counseling are crucial for accurate diagnosis and appropriate management. Further exploration of associated problems, including hearing loss and developmental delay, is warranted in patients with these mutations.
RESUMO
A newborn of unknown gestational age and unknown chronological age was admitted to the neonatal intensive care unit after presenting to the emergency department for evaluation and concern for neglect. The infant was found at home by authorities with no adult caretaker. As part of routine newborn care, this infant was noted to have an abnormal newborn metabolic screen. Subsequent genetic testing confirmed an inborn error of metabolism. When family and social history became available, it was determined that the mother and putative father were genetically related. This case report discusses newborn metabolic screening and inborn errors of metabolism and their relationship to consanguinity.
