Truncations downstream of this position have been classified as pathogenic by our laboratory (e.g. c.778dupC, p.Gln260fsX10; c.845delT, p.Leu282fsX2; c.1145_1151delCCCAACT, p.Ser382fsX24). One in silico tool predicts a damaging outcome for this variant. This variant was found in 1/246180 control chromosomes at a frequency of 0.0000041 in gnomAD, which does not exceed the estimated maximal expected allele frequency of a pathogenic ATP7B variant (0.0054006). This variant was reported in multiple WD patients (Coffey_2013, Nanji_1997, Forbes_2014). In addition, one clinical diagnostic laboratory/reputable database classified this variant as pathogenic. Taken together, this variant is classified as pathogenic.
Invitae RCV000194439 SCV001205573 pathogenic Wilson disease 2023-10-09 criteria provided, single submitter clinical testing This sequence change creates a premature translational stop signal (p.Arg723Glufs*32) in the ATP7B gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in ATP7B are known to be pathogenic (PMID: 10441329, 16283883). This variant is present in population databases (rs768729972, gnomAD 0.0009%). This premature translational stop signal has been observed in individual(s) with Wilson disease (PMID: 9199563, 24555712, 30230192). It has also been observed to segregate with disease in related individuals. This variant is also known as 2164insT . ClinVar contains an entry for this variant (Variation ID: 210483). For these reasons, this variant has been classified as Pathogenic.
