Genes affected
NIN (HGNC:14906): (ninein) This gene encodes one of the proteins important for centrosomal function. This protein is important for positioning and anchoring the microtubules minus-ends in epithelial cells. Localization of this protein to the centrosome requires three leucine zippers in the central coiled-coil domain. Multiple alternatively spliced transcript variants that encode different isoforms have been reported. [provided by RefSeq, Jul 2008]

Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpJan 09, 2024This sequence change replaces asparagine, which is neutral and polar, with aspartic acid, which is acidic and polar, at codon 2103 of the NIN protein (p.Asn2103Asp). This variant is present in population databases (rs777084348, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with NIN-related conditions. ClinVar contains an entry for this variant (Variation ID: 2155912). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
