RCV001328064 | SCV001449252 | pathogenic | Alport syndrome | 2018-09-06 | no assertion criteria provided | clinical testing | This patient is also heterozygous for a second variant in the COL4A4 gene, c.555dup. This frameshifting variant is predicted to create a premature stop codon 61 amino acids downstream (p.Gln186Serfs*62), and may result in a null allele due to nonsense-mediated mRNA decay. To our knowledge, this variant has not been previously reported. However, other COL4A4 truncating variants downstream have been reported in patients with autosomal recessive Alport syndrome (Storey et al 2013 J Am Soc Nephrol 24:1945-54) |
