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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 12, 2024The c.916C>G (p.R306G) alteration is located in exon 10 (coding exon 10) of the NGDN gene. This alteration results from a C to G substitution at nucleotide position 916, causing the arginine (R) at amino acid position 306 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
