Genetic Variant SLC39A2:p.Leu43Gln (chr14-20999754-T-A) – ACMG Classification: Benign (-12 pts)

Variant summary

Our verdict is Benign. The variant received -12 ACMG points: 0P and 12B. BP4_StrongBS1BS2

The NM_014579.4(SLC39A2):c.128T>A(p.Leu43Gln) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0016 in 1,613,950 control chromosomes in the GnomAD database, including 40 homozygotes. In-silico tool predicts a benign outcome for this variant. 16/21 in silico tools predict a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. L43R) has been classified as Benign.

Genes affected

SLC39A2 (HGNC:17127): (solute carrier family 39 member 2) This gene encodes a member of the ZIP family of metal ion transporters. The encoded protein functions as a zinc transporter. Mutations in this gene may be associated with susceptibility to carotid artery disease. Multiple transcript variants have been described. [provided by RefSeq, Mar 2010]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -12 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.004229337).

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00847 (1289/152124) while in subpopulation AFR AF = 0.0287 (1189/41498). AF 95% confidence interval is 0.0273. There are 19 homozygotes in GnomAd4. There are 592 alleles in the male GnomAd4 subpopulation. Median coverage is 31. This position passed quality control check.

BS2

High Homozygotes in GnomAd4 at 19 AR gene
