The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This sequence change affects codon 39 of the NPRL3 mRNA. It is a 'silent' change, meaning that it does not change the encoded amino acid sequence of the NPRL3 protein. It affects a nucleotide within the consensus splice site. This variant has not been reported in the literature in individuals affected with NPRL3-related conditions. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant is not likely to affect RNA splicing. ClinVar contains an entry for this variant (Variation ID: 542801). -
