Is GLA p.Ser401Ter (c.1202C>G) pathogenic?

GLA p.Ser401Ter (c.1202C>G) is classified Pathogenic/Likely pathogenic in GLA (ClinVar, Multiple submitters, 2 submitters; last evaluated 2026-09-08). Absent from gnomAD v4.1; Associated with Fabry disease.

What condition is associated with GLA p.Ser401Ter (c.1202C>G)?

GLA p.Ser401Ter (c.1202C>G) is associated with Fabry disease (ClinVar).

How common is GLA p.Ser401Ter (c.1202C>G) in the general population?

GLA p.Ser401Ter (c.1202C>G) is absent from gnomAD v4.1 (gnomAD).

How is Fabry disease inherited?

Typically X-linked dominant, X-linked recessive (Orphanet). A genetic counselor can assess individual risk for a family.

Computational evidence

Protein change
Missense predictors do not apply to this variant type; conservation carries the signal.
Consequence	nonsense (stop-gain)	predicted loss-of-function in a haploinsufficient gene (ClinGen)
NMD	escapes	premature termination codon in the last exon (7 of 7) — the truncated protein is likely expressed. PVS1 input, not an applied code
Splicing
SpliceAI	—	not assessed · no allele here is in the release
Constraint at this position
Conservation	phyloP 6.6	GERP 3.2, phastCons 1
Overall
CADD	34.0	PHRED · no single calibrated threshold — expert panels disagree

Predicted loss-of-function is descriptive, not an applied PVS1 code.
