What condition is associated with STAT5B p.Asn385= (c.1155C>T)?

STAT5B p.Asn385= (c.1155C>T) is associated with growth hormone insensitivity with immune dysregulation 1, autosomal recessive (ClinVar).

How common is STAT5B p.Asn385= (c.1155C>T) in the general population?

STAT5B p.Asn385= (c.1155C>T) is ultra-rare (popmax 0.049%, eas) (gnomAD).

How is Laron syndrome with immunodeficiency inherited?

Typically Autosomal dominant, 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.
