The c.400C>T (p.P134S) alteration is located in exon 4 (coding exon 4) of the LY86 gene. This alteration results from a C to T substitution at nucleotide position 400, causing the proline (P) at amino acid position 134 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
