Is HAL p.Val146= (c.438G>A) pathogenic?

HAL p.Val146= (c.438G>A) is classified Uncertain significance in HAL (ClinVar, Single submitter, 1 submitter; last evaluated 2018-01-13). Very rare (popmax 8.49e-05%, nfe); Associated with histidinemia.

What condition is associated with HAL p.Val146= (c.438G>A)?

HAL p.Val146= (c.438G>A) is associated with histidinemia (ClinVar).

How common is HAL p.Val146= (c.438G>A) in the general population?

HAL p.Val146= (c.438G>A) is very rare (popmax 8.49e-05%, nfe) (gnomAD).

How is Histidinemia inherited?

Typically 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.
