Is RD3 p.Ser69Phe (c.206C>T) pathogenic?

RD3 p.Ser69Phe (c.206C>T) is classified Uncertain significance in RD3 (ClinVar, Single submitter, 1 submitter; last evaluated 2021-02-08). AlphaMissense: likely benign (0.133); Absent from gnomAD v4.1; Associated with Leber congenital amaurosis 12.

What condition is associated with RD3 p.Ser69Phe (c.206C>T)?

RD3 p.Ser69Phe (c.206C>T) is associated with Leber congenital amaurosis 12 (ClinVar).

How common is RD3 p.Ser69Phe (c.206C>T) in the general population?

RD3 p.Ser69Phe (c.206C>T) is absent from gnomAD v4.1 (gnomAD).

How is Leber congenital amaurosis inherited?

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

What do computational predictors say about RD3 p.Ser69Phe (c.206C>T)?

AlphaMissense predicts likely benign (score 0.133) — an in-silico prediction, not a clinical call.

Protein change
AlphaMissense	0.133	likely benign
REVEL	0.061	moderately benign-leaning
SaProt	LLR -7.79	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.
