Collection Method: clinical testing

The c.232C>T (p.P78S) alteration is located in exon 3 (coding exon 3) of the LIPK gene. This alteration results from a C to T substitution at nucleotide position 232, causing the proline (P) at amino acid position 78 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
