Genes affected
UNC5A (HGNC:12567): (unc-5 netrin receptor A) UNC5A belongs to a family of netrin-1 (MIM 601614) receptors thought to mediate the chemorepulsive effect of netrin-1 on specific axons. For more information on UNC5 proteins, see UNC5C (MIM 603610).[supplied by OMIM, Apr 2004]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 06, 2024The c.499G>C (p.V167L) alteration is located in exon 4 (coding exon 4) of the UNC5A gene. This alteration results from a G to C substitution at nucleotide position 499, causing the valine (V) at amino acid position 167 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
