| sphingomyelin phosphodiesterase |
According to the submitter, biochemical test results for this subject showed decreased enzyme activity. EC Number: 3.1.4.12; 8% activity. |
| |
| Remarks |
8% of normal sphingomyelinase activity & deficient phospholipase C activity in fibroblasts; type A; tested and negative for the three most common mutations in SMPD1, i.e., R496L (607608.0001), L302P (607608.0010), and P330fsX382 (607608.0011). |
