Variant summary

Our verdict is Pathogenic. The variant received 14 ACMG points: 14P and 0B. PM1PM5PP3_ModeratePP5_Very_Strong

The NM_006767.4(LZTR1):​c.1397G>A​(p.Arg466Gln) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000031 in 1,612,590 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R466L) has been classified as Likely pathogenic.

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]

ACMG classification

Classification was made for transcript

Our verdict: Pathogenic. The variant received 14 ACMG points.

PM1
In a hotspot region, there are 2 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 1 benign, 53 uncertain in NM_006767.4
PM5
Other missense variant is known to change same aminoacid residue: Variant chr22-20993967-G-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 1312561.
PP3
MetaRNN computational evidence supports a deleterious effect, 0.923
PP5
Variant 22-20993967-G-A is Pathogenic according to our data. Variant chr22-20993967-G-A is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 101038.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
