Ambry Genetics

Dec 13, 2022

The c.697G>A (p.A233T) alteration is located in exon 5 (coding exon 5) of the UNC5A gene. This alteration results from a G to A substitution at nucleotide position 697, causing the alanine (A) at amino acid position 233 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
