Genes affected

NRG4 (HGNC:29862): (neuregulin 4) The neuregulins, including NRG4, activate type-1 growth factor receptors (see EGFR; MIM 131550) to initiating cell-to-cell signaling through tyrosine phosphorylation (Harari et al., 1999 [PubMed 10348342]).[supplied by OMIM, Mar 2008]

Ambry Genetics

Aug 09, 2021

The c.167A>C (p.Q56P) alteration is located in exon 4 (coding exon 3) of the NRG4 gene. This alteration results from a A to C substitution at nucleotide position 167, causing the glutamine (Q) at amino acid position 56 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
