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]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -20 ACMG points.

BP4
Computational evidence support a benign effect (REVEL=0.009).
BP6
Variant 9-128247952-C-T is Benign according to our data. Variant chr9-128247952-C-T is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 382866.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BS1
Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00887 (1351/152288) while in subpopulation AFR AF = 0.0308 (1279/41532). AF 95% confidence interval is 0.0294. There are 23 homozygotes in GnomAd4. There are 599 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
