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 -9 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.005154252).
BP6
Variant 1-235805919-T-C is Benign according to our data. Variant chr1-235805919-T-C is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 525170.
BS1
Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.000552 (84/152260) while in subpopulation AFR AF = 0.00185 (77/41562). AF 95% confidence interval is 0.00152. There are 0 homozygotes in GnomAd4. There are 41 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
