dbSNP rs704010: ZMIZ1:c.-337+12121T>A (chr10-79081391-T-A) – ACMG Classification: Likely_benign (-2 pts)

Variant summary

Our verdict is The variant received -2 classification points (ACMG Germline Pathogenicity v2019). PM2BP4_Strong

The NM_020338.4(ZMIZ1):c.-337+12121T>A variant causes a intron change involving the alteration of a non-conserved nucleotide. The variant is absent from the gnomAD population database at sites with sufficient sequencing coverage. In-silico predictor (BayesDel (noAF)) classifies this variant as likely benign. Splicing prediction tools (SpliceAI) predict no significant impact on normal splicing. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

Genes affected

ZMIZ1 (HGNC:16493): (zinc finger MIZ-type containing 1) This gene encodes a member of the PIAS (protein inhibitor of activated STAT) family of proteins. The encoded protein regulates the activity of various transcription factors, including the androgen receptor, Smad3/4, and p53. The encoded protein may also play a role in sumoylation. A translocation between this locus on chromosome 10 and the protein tyrosine kinase ABL1 locus on chromosome 9 has been associated with acute lymphoblastic leukemia. [provided by RefSeq, Mar 2010]

Classification according to ACMG Germline Pathogenicity v2019

Classification was made for transcript:

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

Show applied only (2)

Apply	Criterion Code & Title / Strength	Strength	Rationale / Clinical Context
	PM2Absent/extremely low in population databases		Absent from gnomAD (AD/XL gene) — PM2; Absent from gnomAD at well-covered site (MOI: AD/XL) (threshold 0.0001) — PM2 moderate.
	BP4Computational evidence suggests no impact		Computational evidence supports benign — no pathogenic computational or splicing signal (BP4); Splicing verdict: benign (Strong).; Germline computational verdict: benign (Strong).
