Variant summary

Our verdict is Benign. The variant received -20 ACMG points: 0P and 20B. BP4_StrongBP6_Very_StrongBS1BS2

The NM_005857.5(ZMPSTE24):c.8T>C(p.Met3Thr) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000954 in 1,613,840 control chromosomes in the GnomAD database, including 4 homozygotes. In-silico tool predicts a benign outcome for this variant. 15/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. M3L) has been classified as Uncertain significance.

Genes affected

ZMPSTE24 (HGNC:12877): (zinc metallopeptidase STE24) This gene encodes a member of the peptidase M48A family. The encoded protein is a zinc metalloproteinase involved in the two step post-translational proteolytic cleavage of carboxy terminal residues of farnesylated prelamin A to form mature lamin A. Mutations in this gene have been associated with mandibuloacral dysplasia and restrictive dermopathy. [provided by RefSeq, Jul 2008]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -20 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.01731202).

BP6

Variant 1-40258279-T-C is Benign according to our data. Variant chr1-40258279-T-C is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 437336.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BS1

Variant frequency is greater than expected in population sas. GnomAdExome4 allele frequency = 0.000103 (150/1461642) while in subpopulation SAS AF = 0.00167 (144/86258). AF 95% confidence interval is 0.00145. There are 3 homozygotes in GnomAdExome4. There are 105 alleles in the male GnomAdExome4 subpopulation. Median coverage is 31. This position passed quality control check.

BS2

High Homozygotes in GnomAdExome4 at 3 AR,AD gene
