What condition is associated with STAT1 p.Ser745= (c.2235T>C)?

STAT1 p.Ser745= (c.2235T>C) is associated with autoimmune enteropathy and endocrinopathy - susceptibility to chronic infections syndrome, immunodeficiency 31B, Mendelian susceptibility to mycobacterial diseases due to partial STAT1 deficiency (ClinVar).

How common is STAT1 p.Ser745= (c.2235T>C) in the general population?

STAT1 p.Ser745= (c.2235T>C) is very rare (popmax 8.48e-05%, nfe) (gnomAD).

STAT1 p.Ser745=

Q: How is STAT1-related autoimmune enteropathy and endocrinopathy-susceptibility to chronic infections syndrome inherited?

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

Protein change
Missense predictors do not apply to this variant type; conservation carries the signal.
Splicing
SpliceAI	<0.2	no splice effect predicted · four deltas, not one · how we know

Population frequency

gnomAD v4.1 · exomes + genomes

Grpmax group 8.48e-05% European (non-Finnish) · 1/1,179,562 alleles

Overall 6.2e-05% 1/1,613,668 alleles · very rare exomes 1/1,461,338 · genomes 0/152,330 · joint denominator

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.
