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]

Ambry Genetics

Jun 29, 2023

The c.6138A>T (p.K2046N) alteration is located in exon 30 (coding exon 28) of the NIN gene. This alteration results from a A to T substitution at nucleotide position 6138, causing the lysine (K) at amino acid position 2046 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
