Genes affected

SLC3A2 (HGNC:11026): (solute carrier family 3 member 2) This gene is a member of the solute carrier family and encodes a cell surface, transmembrane protein. The protein exists as the heavy chain of a heterodimer, covalently bound through di-sulfide bonds to one of several possible light chains. The encoded transporter plays a role in regulation of intracellular calcium levels and transports L-type amino acids. Alternatively spliced transcript variants, encoding different isoforms, have been characterized. [provided by RefSeq, Nov 2010]

ACMG classification

Verdict is Benign. Variant got -14 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.9).
• BP6: Variant 11-62876882-G-A is Benign according to our data. Variant chr11-62876882-G-A is described in ClinVar as [Benign]. Clinvar id is 781000.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.0103 (1565/152240) while in subpopulation AFR AF= 0.0358 (1488/41548). AF 95% confidence interval is 0.0343. There are 18 homozygotes in gnomad4. There are 717 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High AC in GnomAd at 1566 AD gene.
