Condition	Inheritance	Intervention Categories	Intervention/Rationale	Manifestation Categories	References
Epileptic encephalopathy, early infantile, 3	AR	General	Genetic knowledge may be beneficial related to issues such as selection of optimal supportive care, informed medical decision-making, prognostic considerations, and avoidance of unnecessary testing	Neurologic	15592994; 19780765; 24596948
As with other conditions involving seizures, optimal seizure control is beneficial, and awareness of genetic causes may help with medication selection

Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the SLC25A22 gene is commonly pathogenic or not.

In the table, we include only reliable ClinVar variants with their consequences to MANE Select, Mane Plus Clinical transcripts, or transcripts with TSL equals 1. Click the count to view the source variants.

Warning: slight differences between displayed counts and the number of variants in ClinVar may occur, primarily due to (1) the application of a different transcript and/or consequence by our variant effect predictor or (2) differences in clinical significance: we classify Benign/Likely benign variants as Likely benign and Pathogenic/Likely pathogenic variants as Likely pathogenic.
