Variant summary: ZBTB24 c.146G>A (p.Arg49Gln) results in a conservative amino acid change in the encoded protein sequence. Three of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 0.0067 in 251482 control chromosomes, predominantly at a frequency of 0.0091 within the Non-Finnish European subpopulation in the gnomAD database, including 10 homozygotes. The observed variant frequency within Non-Finnish European control individuals in the gnomAD database is approximately 8 fold of the estimated maximal expected allele frequency for a pathogenic variant in ZBTB24 causing ICF Syndrome, Type 2 phenotype (0.0011), strongly suggesting that the variant is a benign polymorphism found primarily in populations of Non-Finnish European origin. Although reported in the literature, to our knowledge, no penetrant association of c.146G>A in individuals affected with ICF Syndrome, Type 2 and no experimental evidence demonstrating its impact on protein function have been reported. Three clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. All laboratories classified the variant as benign. Based on the evidence outlined above, the variant was classified as benign. -
