Genes affected

NELL2 (HGNC:7751): (neural EGFL like 2) The protein encoded by this gene is a glycoprotein containing several von Willebrand factor C domains and epidermal growth factor (EGF)-like domains. The encoded protein acts as a homotrimer and is found in the cytoplasm. Several variants encoding a few different isoforms exist, and at least one isoform appears to be a secreted protein. Studies in mouse suggest that this protein plays a role in neural cell growth and differentiation as well as in oncogenesis. [provided by RefSeq, Feb 2009]

The c.2446C>T (p.R816C) alteration is located in exon 20 (coding exon 20) of the NELL2 gene. This alteration results from a C to T substitution at nucleotide position 2446, causing the arginine (R) at amino acid position 816 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
