Variant summary

Our verdict is Likely benign. Variant got -2 ACMG points: 2P and 4B. PM2 BP4_Strong

The NM_001376113.1(ZBTB38):​c.955T>A​(p.Ser319Thr) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. 15/21 in silico tools predict a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. S319A) has been classified as Likely benign.

• Frequency: Genomes: not found (cov: 32)
• Consequence: ZBTB38 NM_001376113.1 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: -0.609

Genes affected

ZBTB38 (HGNC:26636): (zinc finger and BTB domain containing 38) The protein encoded by this gene is a zinc finger transcriptional activator that binds methylated DNA. The encoded protein can form homodimers or heterodimers through the zinc finger domains. In mouse, inhibition of this protein has been associated with apoptosis in some cell types.

ACMG classification

Verdict is Likely_benign. Variant got -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.049429476).
