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]

Classification according to ACMG Germline Pathogenicity v2019

Classification was made for transcript:

Our verdict: Likely_benign. The variant received -2 points.

PM2Absent/extremely low in population databases
Absent from gnomAD (AD/XL gene) — PM2; Absent from gnomAD at well-covered site (MOI: AD+AR) (base 0.0001, raised to 0.00015 by highest known P/LP ClinVar AF 0.00015) — PM2 moderate.
BP4Computational evidence suggests no impact
Computational evidence supports benign — no pathogenic computational or splicing signal (BP4); No splicing predictor data available.; Germline computational verdict: benign (Strong).
