Description

NM_000495.4(COL4A5):c.515delA(N172Ifs*31) is expected to be pathogenic in the context of X-linked Alport syndrome. This variant is predicted to lead to an abnormal or absent protein product due to the creation of a premature termination codon in COL4A5, a gene where loss-of-function variants are known to be pathogenic. Please note: this variant was assessed in the context of healthy population screening.
