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.2101G>A (p.E701K) alteration is located in exon 18 (coding exon 18) of the NOC2L gene. This alteration results from a G to A substitution at nucleotide position 2101, causing the glutamic acid (E) at amino acid position 701 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
