What condition is associated with MOGS p.Val210= (c.630G>A)?

MOGS p.Val210= (c.630G>A) is associated with MOGS-congenital disorder of glycosylation (ClinVar).

How common is MOGS p.Val210= (c.630G>A) in the general population?

MOGS p.Val210= (c.630G>A) is very rare (popmax 0.00223%, eas) (gnomAD).

How is MOGS-CDG 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.
