Genes affected

SLC39A5 (HGNC:20502): (solute carrier family 39 member 5) The protein encoded by this gene belongs to the ZIP family of zinc transporters that transport zinc into cells from outside, and play a crucial role in controlling intracellular zinc levels. Zinc is an essential cofactor for many enzymes and proteins involved in gene transcription, growth, development and differentiation. Mutations in this gene have been associated with autosomal dominant high myopia (MYP24). Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Sep 2014]

ACMG classification

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.0020042956).
• BP6: Variant 12-56231284-T-C is Benign according to our data. Variant chr12-56231284-T-C is described in ClinVar as [Benign]. Clinvar id is 776719.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00713 (1084/152112) while in subpopulation AFR AF= 0.0248 (1029/41520). AF 95% confidence interval is 0.0235. There are 20 homozygotes in gnomad4. There are 539 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High AC in GnomAd4 at 1084 AD gene.
