The c.871A>T (p.S291C) alteration is located in exon 7 (coding exon 7) of the KHDRBS2 gene. This alteration results from a A to T substitution at nucleotide position 871, causing the serine (S) at amino acid position 291 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
