Furthermore, specific lab or imaging studies may be needed for specific HCM phenocopies: for example, for amyloidosis subtype diagnosis, serum and urine protein electrophoresis with immunofixation and free light chain dosage and bone scintigraphy with 99mTc-DPD/PYP/HMDP are mandatory (Figure 3). Here, TNFSF14 is linked to amyloidosis.
