The c.313G>A (p.A105T) alteration is located in exon 3 (coding exon 3) of the UNC93A gene. This alteration results from a G to A substitution at nucleotide position 313, causing the alanine (A) at amino acid position 105 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
