LAMB3 and osteogenesis imperfecta type 5: This patient had a previously undescribed mutation c.1903 C>T: p.Arg635 * in a heterozygous state in the laminin B3 (LAMB3) gene, mutations that are found in bullous epidermolysis and amylogenesis imperfecta [21], resulting in a milder clinical manifestation of OI type V. This patient had no skin problems, and though some dental anomalies were present, the dental condition did not require medical intervention until in the last year, when caries of several localizations appeared.
