Is BIN1 p.Ser79Phe (c.236C>T) pathogenic?

BIN1 p.Ser79Phe (c.236C>T) is classified Uncertain significance in BIN1 (ClinVar, Single submitter, 1 submitter; last evaluated 2022-03-18). AlphaMissense: likely pathogenic (0.9608); Very rare (popmax 0.0011%, sas); Associated with myopathy, centronuclear, 2.

What condition is associated with BIN1 p.Ser79Phe (c.236C>T)?

BIN1 p.Ser79Phe (c.236C>T) is associated with myopathy, centronuclear, 2 (ClinVar).

How common is BIN1 p.Ser79Phe (c.236C>T) in the general population?

BIN1 p.Ser79Phe (c.236C>T) is very rare (popmax 0.0011%, sas) (gnomAD).

How is Autosomal recessive centronuclear myopathy inherited?

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

What do computational predictors say about BIN1 p.Ser79Phe (c.236C>T)?

AlphaMissense predicts likely pathogenic (score 0.9608) — an in-silico prediction, not a clinical call.

AlphaMissense	0.9608	likely pathogenic
REVEL	0.7	pathogenic-leaning
SaProt	LLR -13.60	damaging
⇒ AlphaMissense, REVEL and SaProt all call this damaging.

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.

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.
