Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.827C>T (p.P276L) alteration is located in exon 6 (coding exon 6) of the LDLRAD3 gene. This alteration results from a C to T substitution at nucleotide position 827, causing the proline (P) at amino acid position 276 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
