Genes affected

SLC31A1 (HGNC:11016): (solute carrier family 31 member 1) The protein encoded by this gene is a high-affinity copper transporter found in the cell membrane. The encoded protein functions as a homotrimer to effect the uptake of dietary copper. [provided by RefSeq, Aug 2011]

SLC31A1 Gene-Disease associations (from GenCC):

• neurodegeneration and seizures due to copper transport defect

  Inheritance: Unknown, AR Classification: MODERATE, LIMITED Submitted by: Labcorp Genetics (formerly Invitae), G2P, PanelApp Australia

LOC107987119 (HGNC:):

ACMG classification

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

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.79).
• BS1: Variant frequency is greater than expected in population eas. GnomAd4 allele frequency = 0.00137 (209/152196) while in subpopulation EAS AF = 0.0358 (185/5174). AF 95% confidence interval is 0.0315. There are 2 homozygotes in GnomAd4. There are 129 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
• BS2: High Homozygotes in GnomAd4 at 2 AR,Unknown gene
