Genes affected

NOC2L (HGNC:24517): (NOC2 like nucleolar associated transcriptional repressor) Histone modification by histone acetyltransferases (HAT) and histone deacetylases (HDAC) can control major aspects of transcriptional regulation. NOC2L represents a novel HDAC-independent inhibitor of histone acetyltransferase (INHAT) (Hublitz et al., 2005 [PubMed 16322561]).[supplied by OMIM, Mar 2008]

The c.1883G>A (p.R628Q) alteration is located in exon 16 (coding exon 16) of the NOC2L gene. This alteration results from a G to A substitution at nucleotide position 1883, causing the arginine (R) at amino acid position 628 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
