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]

Collection Method: clinical testing

The c.188T>A (p.I63K) alteration is located in exon 3 (coding exon 3) of the NELL1 gene. This alteration results from a T to A substitution at nucleotide position 188, causing the isoleucine (I) at amino acid position 63 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
