Dec 27, 2022

The c.503C>T (p.P168L) alteration is located in exon 2 (coding exon 2) of the LYSMD2 gene. This alteration results from a C to T substitution at nucleotide position 503, causing the proline (P) at amino acid position 168 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
