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]

ACMG classification

Verdict is Uncertain_significance. Variant got 3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in gene, where missense usually causes diseases (based on misZ statistic), ZMIZ1. . Gene score misZ 3.3882 (greater than the threshold 3.09). Trascript score misZ 4.1342 (greater than threshold 3.09). GenCC has associacion of gene with syndromic intellectual disability, neurodevelopmental disorder with dysmorphic facies and distal skeletal anomalies, complex neurodevelopmental disorder.

The c.151C>A (p.Q51K) alteration is located in exon 6 (coding exon 2) of the ZMIZ1 gene. This alteration results from a C to A substitution at nucleotide position 151, causing the glutamine (Q) at amino acid position 51 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
