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. [provided by RefSeq, Apr 2017]

ACMG classification

Verdict is Pathogenic. Variant got 13 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), ZSWIM6. . Gene score misZ 4.1751 (greater than the threshold 3.09). Trascript score misZ 3.277 (greater than threshold 3.09). GenCC has associacion of gene with acromelic frontonasal dysostosis, neurodevelopmental disorder with movement abnormalities, abnormal gait, and autistic features.
• 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.
