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]

The c.458C>T (p.A153V) alteration is located in exon 4 (coding exon 4) of the NELL1 gene. This alteration results from a C to T substitution at nucleotide position 458, causing the alanine (A) at amino acid position 153 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
