Is CPT1A p.Pro510Ser (c.1528C>T) pathogenic?

CPT1A p.Pro510Ser (c.1528C>T) is classified Uncertain significance in CPT1A (ClinVar, Single submitter, 1 submitter; last evaluated 2020-03-20). AlphaMissense: likely benign (0.0866); Absent from gnomAD v4.1; Associated with carnitine palmitoyl transferase 1A deficiency.

What condition is associated with CPT1A p.Pro510Ser (c.1528C>T)?

CPT1A p.Pro510Ser (c.1528C>T) is associated with carnitine palmitoyl transferase 1A deficiency (ClinVar).

How common is CPT1A p.Pro510Ser (c.1528C>T) in the general population?

CPT1A p.Pro510Ser (c.1528C>T) is absent from gnomAD v4.1 (gnomAD).

How is Carnitine palmitoyl transferase 1A deficiency inherited?

Typically Autosomal recessive (Orphanet). A genetic counselor can assess individual risk for a family.

What do computational predictors say about CPT1A p.Pro510Ser (c.1528C>T)?

AlphaMissense predicts likely benign (score 0.0866) — an in-silico prediction, not a clinical call.
