Genes affected
GRB14 (HGNC:4565): (growth factor receptor bound protein 14) The product of this gene belongs to a small family of adapter proteins that are known to interact with a number of receptor tyrosine kinases and signaling molecules. This gene encodes a growth factor receptor-binding protein that interacts with insulin receptors and insulin-like growth-factor receptors. This protein likely has an inhibitory effect on receptor tyrosine kinase signaling and, in particular, on insulin receptor signaling. This gene may play a role in signaling pathways that regulate growth and metabolism. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2014]

The c.1534G>A (p.D512N) alteration is located in exon 14 (coding exon 14) of the GRB14 gene. This alteration results from a G to A substitution at nucleotide position 1534, causing the aspartic acid (D) at amino acid position 512 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
