Collection Method: clinical testing

The c.178C>T (p.P60S) alteration is located in exon 2 (coding exon 2) of the LIX1 gene. This alteration results from a C to T substitution at nucleotide position 178, causing the proline (P) at amino acid position 60 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
