ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -2 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.31994772).
BS1
Variant frequency is greater than expected in population amr. GnomAd4 allele frequency = 0.000223 (34/152280) while in subpopulation AMR AF = 0.000327 (5/15298). AF 95% confidence interval is 0.000218. There are 0 homozygotes in GnomAd4. There are 14 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

Immunodeficiency-centromeric instability-facial anomalies syndrome 2 Uncertain:1
Aug 23, 2022
Labcorp Genetics (formerly Invitae), Labcorp
Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 413 of the ZBTB24 protein (p.Arg413Cys). This variant is present in population databases (rs149690823, gnomAD 0.03%). 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: 539531). 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: "Possibly 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. -
