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]

Ambry Genetics

May 18, 2022

The c.208G>A (p.A70T) alteration is located in exon 2 (coding exon 2) of the UNC5A gene. This alteration results from a G to A substitution at nucleotide position 208, causing the alanine (A) at amino acid position 70 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
