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 GeneticsJul 14, 2021The c.68G>T (p.C23F) alteration is located in exon 3 (coding exon 2) of the NRG4 gene. This alteration results from a G to T substitution at nucleotide position 68, causing the cysteine (C) at amino acid position 23 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
