The c.523C>T (p.P175S) 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 523, causing the proline (P) at amino acid position 175 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
