Is CTRC p.Gly205Asp (c.614G>A) pathogenic?

CTRC p.Gly205Asp (c.614G>A) is classified Uncertain significance in CTRC (ClinVar, Multiple submitters, 2 submitters; last evaluated 2024-10-12). AlphaMissense: likely pathogenic (0.7757); Very rare (popmax 0.000593%, nfe); Associated with hereditary chronic pancreatitis.

What condition is associated with CTRC p.Gly205Asp (c.614G>A)?

CTRC p.Gly205Asp (c.614G>A) is associated with hereditary chronic pancreatitis (ClinVar).

How common is CTRC p.Gly205Asp (c.614G>A) in the general population?

CTRC p.Gly205Asp (c.614G>A) is very rare (popmax 0.000593%, nfe) (gnomAD).

What do computational predictors say about CTRC p.Gly205Asp (c.614G>A)?

AlphaMissense predicts likely pathogenic (score 0.7757) — an in-silico prediction, not a clinical call.

CTRC p.Gly205Asp

Q: How is Autosomal dominant hereditary chronic pancreatitis inherited?

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

Remaining individuals shows a higher raw frequency than the grpmax group above it. gnomAD excludes bottlenecked groups — Finnish, Ashkenazi Jewish, Amish and “Remaining individuals” — from grpmax, because founder effects make their frequencies unrepresentative for filtering. The table is sorted by frequency, so an excluded group can sit above the grpmax row.

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.
