Feb 16, 2023

The c.871C>T (p.R291C) alteration is located in exon 6 (coding exon 5) of the SCML4 gene. This alteration results from a C to T substitution at nucleotide position 871, causing the arginine (R) 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. -
