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 GeneticsJul 13, 2021The c.1267G>A (p.V423I) alteration is located in exon 8 (coding exon 8) of the UNC5A gene. This alteration results from a G to A substitution at nucleotide position 1267, causing the valine (V) at amino acid position 423 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
