| Study Title | Metabolomic profiling of ALG13-CDG brain organoids |
| Study Summary | ALG13-CDG is a rare inborn error of metabolism caused by deficiency of the ALG13 enzyme, which is believed to lead to impaired protein glycosylation. While the disorder has primarily neurological presentation, there is limited knowledge about the specific brain-related changes that result from ALG13 deficiency. We used 3D brain organoids derived from fibroblasts of the individuals with ALG13-CDG to probe the brain-specific metabolic changes in ALG13-CDG. |

Sample Preparation:
| Sampleprep ID: | SP003245 |
| Sampleprep Summary: | Briefly, 4-5 organoids per cell line were collected and washed three times in PBS. The PBS was then removed, the organoids flash frozen and kept in -80 °C prior to metabolomics experiments. The metabolites were extracted using two phase extraction protocol. First, the organoids were transferred to lysing matrix tube and 350 µL of ice-cold extraction buffer (80 % MeOH, IS) was added to the sample. Next, the organoids were lyzed with ribolyzer, the lysate transferred to 1.5 mL Eppendorf tube and placed overnight at -80 °C. Further, the samples were centrifuged at 15,000 rpm, 4 °C, 20 min. 100 µL of supernatant was transferred to a fresh Eppendorf tube and 35 µL of ddH20 was added, followed by 800 µL 100% chloroform. The samples were then vortexed and stored at 4 °C overnight. Next, the polar phase was then used for Liquid Chromatography/Mass Spectrometry (LC/MS). |

| Flow Gradient: | The gradient started with 5% of solvent B and 95% solvent A and remained at 5% B until 2 min post injection. A linear gradient to 37% B was carried out until 7 min and increased to 41% until 14 min. Between 14 and 26 minutes the gradient increased to 95% of B and remained at 95% B for 4 minutes. At 30 min the gradient returned to 5% B. The chromatography was stopped at 40 min |
