Is SLC5A2 p.Cys511Ser (c.1532G>C) pathogenic?

SLC5A2 p.Cys511Ser (c.1532G>C) is classified Uncertain significance in SLC5A2 (ClinVar, Single submitter, 1 submitter). AlphaMissense: likely pathogenic (0.9868); Very rare (popmax 0.00133%, afr); Associated with familial renal glucosuria.

What condition is associated with SLC5A2 p.Cys511Ser (c.1532G>C)?

SLC5A2 p.Cys511Ser (c.1532G>C) is associated with familial renal glucosuria (ClinVar).

How common is SLC5A2 p.Cys511Ser (c.1532G>C) in the general population?

SLC5A2 p.Cys511Ser (c.1532G>C) is very rare (popmax 0.00133%, afr) (gnomAD).

How is Familial renal glucosuria inherited?

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

What do computational predictors say about SLC5A2 p.Cys511Ser (c.1532G>C)?

AlphaMissense predicts likely pathogenic (score 0.9868) — an in-silico prediction, not a clinical call.

ClinVar classifies this uncertain; the computational predictors unanimously lean damaging — 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.
