The c.931G>A (p.A311T) alteration is located in exon 7 (coding exon 7) of the UNC5A gene. This alteration results from a G to A substitution at nucleotide position 931, causing the alanine (A) at amino acid position 311 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
