Collection Method: clinical testing

The c.755C>T (p.P252L) alteration is located in exon 10 (coding exon 10) of the HSD17B12 gene. This alteration results from a C to T substitution at nucleotide position 755, causing the proline (P) at amino acid position 252 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
