Genes affected

NTN4 (HGNC:13658): (netrin 4) This gene encodes a member of the netrin family of proteins, which function in various biological processes including axon guidance, tumorogenesis, and angiogenesis. Netrins are laminin-related proteins that have an N-terminal laminin-type domain, epidermal growth factor-like repeat domain, and a positively charged heparin-binding domain at the C-terminus. The protein encoded by this gene is involved in processes including neurite growth and migration, angiogenesis and mural cell adhesion to endothelial cells. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2016]

The c.1624G>A (p.V542I) alteration is located in exon 9 (coding exon 9) of the NTN4 gene. This alteration results from a G to A substitution at nucleotide position 1624, causing the valine (V) at amino acid position 542 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
