Is LOX p.Pro32Arg (c.95C>G) pathogenic?

LOX p.Pro32Arg (c.95C>G) is classified Uncertain significance in LOX (ClinVar, Single submitter, 1 submitter; last evaluated 2022-12-30). AlphaMissense: likely benign (0.0686); Very rare (popmax 0.00236%, nfe); Associated with aortic aneurysm, familial thoracic 10.

What condition is associated with LOX p.Pro32Arg (c.95C>G)?

LOX p.Pro32Arg (c.95C>G) is associated with aortic aneurysm, familial thoracic 10 (ClinVar).

How common is LOX p.Pro32Arg (c.95C>G) in the general population?

LOX p.Pro32Arg (c.95C>G) is very rare (popmax 0.00236%, nfe) (gnomAD).

What do computational predictors say about LOX p.Pro32Arg (c.95C>G)?

AlphaMissense predicts likely benign (score 0.0686) — an in-silico prediction, not a clinical call.

LOX p.Pro32Arg

Q: How is Familial thoracic aortic aneurysm and aortic dissection inherited?

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

Computational evidence

Protein change

SaProt	LLR -6.37	tolerated
⇒ AlphaMissense, REVEL and SaProt all call this tolerated.

ClinVar classifies this uncertain; the computational predictors unanimously lean tolerated — a triage signal, not a reclassification

AlphaMissense carries the ACMG weight for missense; REVEL and SaProt are independent agreement signals.

Rarity supports pathogenicity (ACMG PM2); frequency above a disease-specific BA1/BS1 threshold argues against it. A variant frequent in one ancestry group can be near-absent in others, so a single global figure can mislead.
