Variant summary

Our verdict is Pathogenic. Variant got 13 ACMG points: 13P and 0B. PM2 PP2 PP3_Moderate PP5_Very_Strong

The NM_020928.2(ZSWIM6):c.3487C>T(p.Arg1163Trp) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R1163Q) has been classified as Uncertain significance.

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.

ACMG classification

Verdict is Pathogenic. Variant got 13 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant where missense usually causes diseases, ZSWIM6
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.848
• PP5: Variant 5-61544156-C-T is Pathogenic according to our data. Variant chr5-61544156-C-T is described in ClinVar as [Likely_pathogenic]. Clinvar id is 155772.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

not provided, no classification provided	phenotyping only	GenomeConnect, ClinGen	-	Variant interpretted as pathogenic and reported on 09/20/2018 by GTR ID 239772. GenomeConnect assertions are reported exactly as they appear on the patient-provided report from the testing laboratory. GenomeConnect staff make no attempt to reinterpret the clinical significance of the variant. -
Likely pathogenic, criteria provided, single submitter	curation	SIB Swiss Institute of Bioinformatics	May 31, 2018	This variant is interpreted as a Likely Pathogenic, for Acromelic frontonasal dysostosis, in Autosomal Dominant manner. The following ACMG Tag(s) were applied: PM6 => Assumed de novo, but without confirmation of paternity and maternity (PMID:25105228). PP3 => Multiple lines of computational evidence support a deleterious effect on the gene or gene product. PM2 => Absent from controls (or at extremely low frequency if recessive) in Exome Sequencing Project, 1000 Genomes Project, or Exome Aggregation Consortium. PS4-Moderate => Observed in multiple unrelated patients. (PMID:25105228,26706854). -
