Is NPHP4 p.Gly710Asp (c.2129G>A) pathogenic?

NPHP4 p.Gly710Asp (c.2129G>A) is classified Uncertain significance in NPHP4 (ClinVar, Multiple submitters, 3 submitters; last evaluated 2024-10-16). AlphaMissense: likely benign (0.1144); Rare (popmax 0.16%, sas); Associated with nephronophthisis 4.

What condition is associated with NPHP4 p.Gly710Asp (c.2129G>A)?

NPHP4 p.Gly710Asp (c.2129G>A) is associated with nephronophthisis 4, Senior-Loken syndrome 4, nephronophthisis (ClinVar).

How common is NPHP4 p.Gly710Asp (c.2129G>A) in the general population?

NPHP4 p.Gly710Asp (c.2129G>A) is rare (popmax 0.16%, sas) (gnomAD).

How is Nephronophthisis inherited?

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

What do computational predictors say about NPHP4 p.Gly710Asp (c.2129G>A)?

AlphaMissense predicts likely benign (score 0.1144) — an in-silico prediction, not a clinical call.

Protein change
AlphaMissense	0.1144	likely benign
REVEL	0.506	indeterminate
SaProt	LLR -8.75	tolerated
⇒ AlphaMissense and SaProt both call this tolerated; REVEL is indeterminate.

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.
