The c.571C>T (p.R191C) alteration is located in exon 4 (coding exon 4) of the SPDYE3 gene. This alteration results from a C to T substitution at nucleotide position 571, causing the arginine (R) at amino acid position 191 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
