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.

BP6

Variant 1-235752126-T-C is Benign according to our data. Variant chr1-235752126-T-C is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 254939.

BP7

Synonymous conserved (PhyloP=0.226 with no splicing effect.

BS1

Variant frequency is greater than expected in population amr. GnomAd4 allele frequency = 0.00108 (165/152266) while in subpopulation AMR AF = 0.00399 (61/15296). AF 95% confidence interval is 0.00319. There are 1 homozygotes in GnomAd4. There are 97 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.

BS2

High Homozygotes in GnomAdExome4 at 2 AR gene
