LAMA3 Antibody

1. This study identified two mutations in two large consanguineous pedigrees. The identification of novel variants in the LAMA3 and PLEC genes expands the mutation spectrum and aids in genetic counseling for patients within the Pakistani population. PMID: 29797489
2. Seventeen percent of the patients exhibited compound heterozygosity or homozygosity for mutations in the LAMA3 gene, 59% carried mutations in both alleles of LAMB3, and 12% were homozygous for mutations in LAMC2. In nine patients with severe generalized JEB, it was not possible to detect two mutations in either LAMA3, LAMB3, or LAMC2, preventing complete clarification of the molecular basis of the disease. PMID: 27375110
