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]

The c.173C>T (p.T58M) alteration is located in exon 6 (coding exon 2) of the ZMIZ1 gene. This alteration results from a C to T substitution at nucleotide position 173, causing the threonine (T) at amino acid position 58 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

This sequence change replaces threonine, which is neutral and polar, with methionine, which is neutral and non-polar, at codon 58 of the ZMIZ1 protein (p.Thr58Met). This variant is present in population databases (rs574206272, gnomAD 0.005%). This variant has not been reported in the literature in individuals affected with ZMIZ1-related conditions. ClinVar contains an entry for this variant (Variation ID: 2366444). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. 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. -
