Collection Method: clinical testing

The c.526C>T (p.R176W) alteration is located in exon 3 (coding exon 3) of the SHD gene. This alteration results from a C to T substitution at nucleotide position 526, causing the arginine (R) at amino acid position 176 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
