Is SLC6A5 p.Pro760= (c.2280A>G) pathogenic?

SLC6A5 p.Pro760= (c.2280A>G) is classified Likely benign in SLC6A5 (ClinVar, Multiple submitters, 2 submitters; last evaluated 2026-02-02). Ultra-rare (popmax 0.0267%, eas); Associated with hyperekplexia 3.

What condition is associated with SLC6A5 p.Pro760= (c.2280A>G)?

SLC6A5 p.Pro760= (c.2280A>G) is associated with hyperekplexia 3 (ClinVar).

How common is SLC6A5 p.Pro760= (c.2280A>G) in the general population?

SLC6A5 p.Pro760= (c.2280A>G) is ultra-rare (popmax 0.0267%, eas) (gnomAD).

How is Hereditary hyperekplexia 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.
