Is PLCE1 p.Ser481Arg (c.1443T>A) pathogenic?

PLCE1 p.Ser481Arg (c.1443T>A) is classified Uncertain significance in PLCE1 (ClinVar, Single submitter, 1 submitter; last evaluated 2023-12-28). AlphaMissense: likely pathogenic (0.7718); Very rare (popmax 0.000169%, nfe); Associated with nephrotic syndrome, type 3.

What condition is associated with PLCE1 p.Ser481Arg (c.1443T>A)?

PLCE1 p.Ser481Arg (c.1443T>A) is associated with nephrotic syndrome, type 3 (ClinVar).

How common is PLCE1 p.Ser481Arg (c.1443T>A) in the general population?

PLCE1 p.Ser481Arg (c.1443T>A) is very rare (popmax 0.000169%, nfe) (gnomAD).

What do computational predictors say about PLCE1 p.Ser481Arg (c.1443T>A)?

AlphaMissense predicts likely pathogenic (score 0.7718) — an in-silico prediction, not a clinical call.

PLCE1 p.Ser481Arg

Q: How is Hereditary steroid-resistant nephrotic syndrome inherited?

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

SaProt	LLR -6.74	tolerated
⇒ AlphaMissense calls this damaging; SaProt does not; REVEL is indeterminate.

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.
