Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This sequence change replaces lysine, which is basic and polar, with arginine, which is basic and polar, at codon 385 of the ZBTB24 protein (p.Lys385Arg). This variant is present in population databases (rs371071024, gnomAD 0.008%). This variant has not been reported in the literature in individuals affected with ZBTB24-related conditions. ClinVar contains an entry for this variant (Variation ID: 539530). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Not Available"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Not Available"). 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. -

Ambry Genetics
Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The c.1154A>G (p.K385R) alteration is located in exon 4 (coding exon 3) of the ZBTB24 gene. This alteration results from a A to G substitution at nucleotide position 1154, causing the lysine (K) at amino acid position 385 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
