Our verdict is Benign. Variant got -12 ACMG points: 0P and 12B. BP4_Strong BA1

The NM_001109809.5(ZFP57):​c.-364+333C>T variant causes a intron change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.293 in 152,060 control chromosomes in the GnomAD database, including 6,871 homozygotes. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

• Frequency: Genomes: 𝑓 0.29 (6871 hom., cov: 31)
• Consequence: ZFP57 NM_001109809.5 intron
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: -1.06

Genes affected

ZFP57 (HGNC:18791): (ZFP57 zinc finger protein) The protein encoded by this gene is a zinc finger protein containing a KRAB domain. Studies in mouse suggest that this protein may function as a transcriptional repressor. Mutations in this gene have been associated with transient neonatal diabetes mellitus type 1 (TNDM1).[provided by RefSeq, Sep 2009]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.91).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.483 is higher than 0.05.
