Description

NM_138694.3(PKHD1):c.776C>G(S259*) is expected to be pathogenic in the context of autosomal recessive polycystic kidney disease, PKHD1-related. This variant is predicted to lead to an abnormal or absent protein product due to the creation of a premature termination codon in PKHD1, 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.
