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]

NOC2L links:

SAMD11 (HGNC:28706): (sterile alpha motif domain containing 11) Predicted to enable several functions, including histone binding activity; protein domain specific binding activity; and protein self-association. Predicted to be involved in negative regulation of transcription, DNA-templated. Predicted to act upstream of or within negative regulation of transcription by RNA polymerase II. Predicted to be active in nucleus. [provided by Alliance of Genome Resources, Apr 2022]

Collection Method: clinical testing

The c.2163G>C (p.E721D) alteration is located in exon 19 (coding exon 19) of the NOC2L gene. This alteration results from a G to C substitution at nucleotide position 2163, causing the glutamic acid (E) at amino acid position 721 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
