Genes affected

SLC39A7 (HGNC:4927): (solute carrier family 39 member 7) The protein encoded by this gene transports zinc from the Golgi and endoplasmic reticulum to the cytoplasm. This transport may be important for activation of tyrosine kinases, some of which could be involved in cancer progression. Therefore, modulation of the encoded protein could be useful as a therapeutic agent against cancer. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2014]

ACMG classification

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.005701214).
• BP6: Variant 6-33201405-T-C is Benign according to our data. Variant chr6-33201405-T-C is described in ClinVar as [Likely_benign]. Clinvar id is 779425.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.00814 (1238/152150) while in subpopulation NFE AF= 0.0132 (900/67968). AF 95% confidence interval is 0.0125. There are 6 homozygotes in gnomad4. There are 575 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 6 AR gene
