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]

The c.308C>T (p.T103M) alteration is located in exon 5 (coding exon 4) of the NRG4 gene. This alteration results from a C to T substitution at nucleotide position 308, causing the threonine (T) at amino acid position 103 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
