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]

Developmental and epileptic encephalopathy, 31 Pathogenic:1
Likely pathogenic, criteria provided, single submitter | clinical testing | Invitae | Feb 04, 2019 | This sequence change replaces serine with asparagine at codon 45 of the DNM1 protein (p.Ser45Asn). The serine residue is highly conserved and there is a small physicochemical difference between serine and asparagine. In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. TThis variant has been reported to affect DNM1 protein function, also known as Dyn1 (PMID: 11553700, 19084268, 29668686). This variant has been observed to be de novo in an individual affected with DNM1-related encephalopathy (PMID: 28667181). ClinVar contains an entry for this variant (Variation ID: 520840). This variant is not present in population databases (ExAC no frequency). - |
