This document discusses identifying mutations in the filaggrin gene through sequence analysis. The filaggrin gene codes for filaggrin proteins that are essential for skin barrier function. Mutations in this gene are linked to conditions like eczema and asthma. The study aims to detect faulty filaggrin genes, identify other human and non-human proteins with similar function to filaggrin, and find identical protein sequences to help develop therapeutic options. Sequence alignment methods like pairwise alignment and BLAST will be used to analyze filaggrin genes and identify similar protein sequences.
