Genes affected
LYST (HGNC:1968): (lysosomal trafficking regulator) This gene encodes a protein that regulates intracellular protein trafficking in endosomes, and may be involved in pigmentation. Mutations in this gene are associated with Chediak-Higashi syndrome, a lysosomal storage disorder. Alternative splicing results in multiple transcript variants, though the full-length nature of some of these variants has not been determined. [provided by RefSeq, Apr 2013]

ACMG classification
Classification was made for transcript
Our verdict: Benign. The variant received -10 ACMG points.
BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.26).
BS1
Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00323 (492/152216) while in subpopulation AFR AF = 0.01 (417/41544). AF 95% confidence interval is 0.00924. There are 3 homozygotes in GnomAd4. There are 231 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
BS2
High Homozygotes in GnomAd4 at 3 AR gene
