Variant summary

Our verdict is Likely benign. The variant received -3 ACMG points: 2P and 5B. PM2 BP4_Strong BP7

The NM_173854.6(SLC41A1):​c.339C>G​(p.Thr113Thr) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as (no stars). Synonymous variant affecting the same amino acid position (i.e. T113T) has been classified as Benign.

Genes affected

SLC41A1 (HGNC:19429): (solute carrier family 41 member 1) Enables magnesium ion transmembrane transporter activity and magnesium:sodium antiporter activity. Involved in cellular magnesium ion homeostasis; cellular response to magnesium ion; and magnesium ion transmembrane transport. Located in basolateral plasma membrane. Part of protein-containing complex. [provided by Alliance of Genome Resources, Apr 2022]
