What condition is associated with GALE p.Phe77= (c.231C>T)?

GALE p.Phe77= (c.231C>T) is associated with galactose epimerase deficiency (ClinVar).

How common is GALE p.Phe77= (c.231C>T) in the general population?

GALE p.Phe77= (c.231C>T) is very rare (popmax 0.00272%, nfe) (gnomAD).

How is Galactose epimerase deficiency inherited?

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

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.
