Variant summary

Our verdict is Pathogenic. The variant received 14 ACMG points: 14P and 0B. PS3PP3_ModeratePP5_Very_Strong

The NM_006767.4(LZTR1):c.264-13G>A variant causes a intron change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000039 in 1,613,824 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★★). ClinVar reports functional evidence for this variant: "SCV002032765: Non-canonical splice site variant demonstrated to result in loss of function (PMID:24362817)" and additional evidence is available in ClinVar.

Genes affected

LZTR1 (HGNC:6742): (leucine zipper like post translational regulator 1) This gene encodes a member of the BTB-kelch superfamily. Initially described as a putative transcriptional regulator based on weak homology to members of the basic leucine zipper-like family, the encoded protein subsequently has been shown to localize exclusively to the Golgi network where it may help stabilize the Gogli complex. Deletion of this gene may be associated with DiGeorge syndrome. [provided by RefSeq, Jul 2008]
