Genes affected

ZSWIM6 (HGNC:29316): (zinc finger SWIM-type containing 6) The protein encoded by this gene contains a zinc finger SWI2/SNF2 and MuDR (SWIM) domain. Proteins with SWIM domains have been found in a diverse number of species and are predicted to interact with DNA or proteins. Mutations in this gene result in acromelic frontonasal dysostosis.

The missense c.28C>A(p.Pro10Thr) variant in ZSWIM6 gene has not been reported previously as a pathogenic variant nor as a benign variant, to our knowledge. The p.Pro10Thr variant is absent in gnomAD Exomes and 1000 Genomes database. This variant has not been reported to the ClinVar database. The amino acid Pro at position 10 is changed to a Thr changing protein sequence and it might alter its composition and physico-chemical properties. The amino acid change p.Pro10Thr in ZSWIM6 is predicted as conserved by GERP++ and PhyloP across 100 vertebrates. For these reasons, this variant has been classified as Variant of Uncertain Significance (VUS). -
