Collection Method: clinical testing

The c.154C>T (p.R52C) alteration is located in exon 1 (coding exon 1) of the SHD gene. This alteration results from a C to T substitution at nucleotide position 154, causing the arginine (R) at amino acid position 52 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
