Collection Method: clinical testing

The c.316C>A (p.P106T) alteration is located in exon 2 (coding exon 2) of the LDLRAD2 gene. This alteration results from a C to A substitution at nucleotide position 316, causing the proline (P) at amino acid position 106 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
