The c.877G>A (p.A293T) alteration is located in exon 7 (coding exon 7) of the KHDRBS2 gene. This alteration results from a G to A substitution at nucleotide position 877, causing the alanine (A) at amino acid position 293 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
