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]

Variant summary: NIN c.5126A>G (p.Asn1709Ser) results in a conservative amino acid change in the encoded protein sequence. Four of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 0.0003 in 251416 control chromosomes. c.5126A>G has been reported in the literature in at least two compound heterozygous siblings affected with Seckel Syndrome 7 (Dauber_2012). These data indicate that the variant may be associated with disease. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publication has been ascertained in the context of this evaluation (PMID: 22933543). Two submitters have cited clinical-significance assessments for this variant to ClinVar after 2014; one submitter classified the variant as likely benign, and one submitter classified the variant as uncertain significance. Based on the evidence outlined above, the variant was classified as uncertain significance. -
