Ambry Genetics

Feb 28, 2023

The c.2995G>A (p.A999T) alteration is located in exon 17 (coding exon 17) of the ROBO4 gene. This alteration results from a G to A substitution at nucleotide position 2995, causing the alanine (A) at amino acid position 999 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
