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]

The c.1874C>A (p.P625H) alteration is located in exon 12 (coding exon 12) of the MDM1 gene. This alteration results from a C to A substitution at nucleotide position 1874, causing the proline (P) at amino acid position 625 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
