Genes affected
DNM1 (HGNC:2972): (dynamin 1) This gene encodes a member of the dynamin subfamily of GTP-binding proteins. The encoded protein possesses unique mechanochemical properties used to tubulate and sever membranes, and is involved in clathrin-mediated endocytosis and other vesicular trafficking processes. Actin and other cytoskeletal proteins act as binding partners for the encoded protein, which can also self-assemble leading to stimulation of GTPase activity. More than sixty highly conserved copies of the 3' region of this gene are found elsewhere in the genome, particularly on chromosomes Y and 15. Alternatively spliced transcript variants encoding different isoforms have been described. [provided by RefSeq, Jul 2008]
CIZ1 (HGNC:16744): (CDKN1A interacting zinc finger protein 1) The protein encoded by this gene is a zinc finger DNA binding protein that interacts with CIP1, part of a complex with cyclin E. The encoded protein may regulate the cellular localization of CIP1. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Apr 2012]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -19 ACMG points.

PP2
Missense variant in the DNM1 gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 39 curated pathogenic missense variants (we use a threshold of 10). The gene has 46 curated benign missense variants. Gene score misZ: 5.1795 (above the threshold of 3.09). Trascript score misZ: 5.021 (above the threshold of 3.09). GenCC associations: The gene is linked to developmental and epileptic encephalopathy, 31, undetermined early-onset epileptic encephalopathy, developmental and epileptic encephalopathy 31B, developmental and epileptic encephalopathy, Lennox-Gastaut syndrome.
BP4
Computational evidence support a benign effect (MetaRNN=0.0020967126).
BP6
Variant 9-128203516-C-A is Benign according to our data. Variant chr9-128203516-C-A is described in ClinVar as [Benign]. Clinvar id is 380950.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BA1
GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.0917 is higher than 0.05.

Significance: Benign
Review Status: criteria provided, single submitter
Collection Method: clinical testing
