Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.284C>T (p.P95L) alteration is located in exon 4 (coding exon 3) of the CLASRP gene. This alteration results from a C to T substitution at nucleotide position 284, causing the proline (P) at amino acid position 95 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
