Is LYST p.Phe2015= (c.6045C>T) pathogenic?

LYST p.Phe2015= (c.6045C>T) is classified Likely benign in LYST (ClinVar, Single submitter, 1 submitter; last evaluated 2024-11-21). Very rare (popmax 0.00439%, sas); Associated with Chediak-Higashi syndrome.

What condition is associated with LYST p.Phe2015= (c.6045C>T)?

LYST p.Phe2015= (c.6045C>T) is associated with Chediak-Higashi syndrome (ClinVar).

How common is LYST p.Phe2015= (c.6045C>T) in the general population?

LYST p.Phe2015= (c.6045C>T) is very rare (popmax 0.00439%, sas) (gnomAD).

How is Chédiak-Higashi syndrome 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.
