The COL4A5 gene homepage

Originally variants in the COL4A5 gene were described based on a 53-exon gene. Variants in the database are based on a 55-exon gene, containing two additional exons (42 and 43), both containing 9 nucleotides. We do not exclude that some variant descriptions were not yet corrected
