Genes affected

NGDN (HGNC:20271): (neuroguidin) Neuroguidin is an EIF4E (MIM 133440)-binding protein that interacts with CPEB (MIM 607342) and functions as a translational regulatory protein during development of the vertebrate nervous system (Jung et al., 2006 [PubMed 16705177]).[supplied by OMIM, Mar 2008]

Oct 20, 2021

The c.61C>T (p.L21F) alteration is located in exon 2 (coding exon 2) of the NGDN gene. This alteration results from a C to T substitution at nucleotide position 61, causing the leucine (L) at amino acid position 21 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
