The c.805G>A (p.A269T) alteration is located in exon 4 (coding exon 3) of the C19orf35 gene. This alteration results from a G to A substitution at nucleotide position 805, causing the alanine (A) at amino acid position 269 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
