Uncertain significance, criteria provided, single submitterclinical testingWomen's Health and Genetics/Laboratory Corporation of America, LabCorpMay 01, 2024Variant summary: ZBTB24 c.1369C>A (p.Arg457Arg) alters a conserved nucleotide located close to a canonical splice site and therefore could affect mRNA splicing, leading to a significantly altered protein sequence. Several computational tools predict a significant impact on normal splicing: Two predict the variant creates a 5' donor site. One predicts the variant strengthens a 5' donor site. One predicts the variant weakens a 5' donor site. However, these predictions have yet to be confirmed by functional studies. The variant was absent in 251446 control chromosomes. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. To our knowledge, no occurrence of c.1369C>A in individuals affected with ICF Syndrome, Type 2 and no experimental evidence demonstrating its impact on protein function have been reported. No submitters have cited clinical-significance assessments for this variant to ClinVar. Based on the evidence outlined above, the variant was classified as uncertain significance. -
