Is PNPLA2 p.Lys367= (c.1101G>A) pathogenic?

PNPLA2 p.Lys367= (c.1101G>A) is classified Likely benign in PNPLA2 (ClinVar, Single submitter, 1 submitter; last evaluated 2023-06-28). Very rare (popmax 0.00476%, sas); Associated with neutral lipid storage myopathy.

What condition is associated with PNPLA2 p.Lys367= (c.1101G>A)?

PNPLA2 p.Lys367= (c.1101G>A) is associated with neutral lipid storage myopathy (ClinVar).

How common is PNPLA2 p.Lys367= (c.1101G>A) in the general population?

PNPLA2 p.Lys367= (c.1101G>A) is very rare (popmax 0.00476%, sas) (gnomAD).

How is Neutral lipid storage disease with myopathy inherited?

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

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.
