Genes affected

STX11 (HGNC:11429): (syntaxin 11) This gene encodes a member of the syntaxin family. Syntaxins have been implicated in the targeting and fusion of intracellular transport vesicles. This family member may regulate protein transport among late endosomes and the trans-Golgi network. Mutations in this gene have been associated with familial hemophagocytic lymphohistiocytosis.

ACMG classification

Classification was made for transcript

Our verdict: Uncertain_significance. The variant received 0 ACMG points.

PM4

Nonframeshift variant in NON repetitive region in NM_003764.4. Strenght limited to Supporting due to length of the change: 1aa.

BS1

Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.000276 (42/152214) while in subpopulation NFE AF = 0.000529 (36/68036). AF 95% confidence interval is 0.000392. There are 0 homozygotes in GnomAd4. There are 14 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
