What condition is associated with SLC13A5 p.Pro445= (c.1335G>C)?

SLC13A5 p.Pro445= (c.1335G>C) is associated with developmental and epileptic encephalopathy, 25 (ClinVar).

How common is SLC13A5 p.Pro445= (c.1335G>C) in the general population?

SLC13A5 p.Pro445= (c.1335G>C) is ultra-rare (popmax 0.0329%, mid) (gnomAD).

SLC13A5 p.Pro445=

Q: How is Non-specific early-onset epileptic encephalopathy 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.
