Is DPM1 p.Pro32Ser (c.94C>T) pathogenic?

DPM1 p.Pro32Ser (c.94C>T) is classified Uncertain significance in DPM1 (ClinVar, Single submitter, 1 submitter; last evaluated 2022-08-16). AlphaMissense: likely pathogenic (0.9768); Absent from gnomAD v4.1; Associated with congenital disorder of glycosylation type 1E.

What condition is associated with DPM1 p.Pro32Ser (c.94C>T)?

DPM1 p.Pro32Ser (c.94C>T) is associated with congenital disorder of glycosylation type 1E (ClinVar).

How common is DPM1 p.Pro32Ser (c.94C>T) in the general population?

DPM1 p.Pro32Ser (c.94C>T) is absent from gnomAD v4.1 (gnomAD).

How is DPM1-CDG inherited?

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

What do computational predictors say about DPM1 p.Pro32Ser (c.94C>T)?

AlphaMissense predicts likely pathogenic (score 0.9768) — 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.
