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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 13, 2023The c.233C>A (p.A78D) alteration is located in exon 4 (coding exon 3) of the NRG4 gene. This alteration results from a C to A substitution at nucleotide position 233, causing the alanine (A) at amino acid position 78 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
