Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 4e-06 in 250364 control chromosomes. c.323G>T has been reported in the literature in the compound heterozygous state in at least one individual affected with Xeroderma Pigmentosum (Satokata_1992). Multiple publications report experimental evidence evaluating an impact on protein function. The most pronounced variant effect results in absent activity (Miura_1999, Van Den Heuvel_2023, Satokata_1992). The following publications have been ascertained in the context of this evaluation (PMID: 10408173, 1339397, 36893274). ClinVar contains an entry for this variant (Variation ID: 993). Based on the evidence outlined above, the variant was classified as likely pathogenic.
