Genes affected

SLC30A8 (HGNC:20303): (solute carrier family 30 member 8) The protein encoded by this gene is a zinc efflux transporter involved in the accumulation of zinc in intracellular vesicles. This gene is expressed at a high level only in the pancreas, particularly in islets of Langerhans. The encoded protein colocalizes with insulin in the secretory pathway granules of the insulin-secreting INS-1 cells. Allelic variants of this gene exist that confer susceptibility to diabetes mellitus, noninsulin-dependent (NIDDM). Several transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Mar 2010]

Ambry Genetics

Dec 07, 2021

The c.235G>A (p.A79T) alteration is located in exon 2 (coding exon 2) of the SLC30A8 gene. This alteration results from a G to A substitution at nucleotide position 235, causing the alanine (A) at amino acid position 79 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
