Genes affected

NELL1 (HGNC:7750): (neural EGFL like 1) This gene encodes a cytoplasmic protein that contains epidermal growth factor (EGF)-like repeats. The encoded heterotrimeric protein may be involved in cell growth regulation and differentiation. A similar protein in rodents is involved in craniosynostosis. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2013]

Ambry Genetics

Apr 08, 2022

The c.664A>G (p.N222D) alteration is located in exon 6 (coding exon 6) of the NELL1 gene. This alteration results from a A to G substitution at nucleotide position 664, causing the asparagine (N) at amino acid position 222 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
