Genetic Variant MDM1:p.Arg698Leu (chr12-68295336-C-A) – ACMG Classification: Uncertain_significance (2 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 2 ACMG points: 2P and 0B. PM2

The NM_001354969.2(MDM1):c.2093G>T(p.Arg698Leu) variant causes a missense change. The variant allele was found at a frequency of 0.00000248 in 1,612,668 control chromosomes in the GnomAD database, with no homozygous occurrence. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R698H) has been classified as Uncertain significance.

Genes affected

MDM1 (HGNC:29917): (Mdm1 nuclear protein) This gene encodes a microtubule-binding nuclear protein that localizes to the centrioles of dividing cells and differentiating multiciliated cells and negatively regulates centriole duplication. The encoded protein is closely associated with the centriole barrel, and resides in the centriole lumen. Naturally-occurring mutations in the orthologous mouse gene are associated with age-related retinal degeneration. [provided by RefSeq, Feb 2019]
