Collection Method: clinical testing

The c.451C>T (p.R151C) alteration is located in exon 4 (coding exon 3) of the HBP1 gene. This alteration results from a C to T substitution at nucleotide position 451, causing the arginine (R) at amino acid position 151 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
