Genes affected
SLC7A8 (HGNC:11066): (solute carrier family 7 member 8) Enables several functions, including neutral amino acid transmembrane transporter activity; thyroid hormone transmembrane transporter activity; and toxin transmembrane transporter activity. Involved in L-alanine import across plasma membrane; L-leucine import across plasma membrane; and thyroid hormone transport. Located in plasma membrane. Part of basolateral plasma membrane and microvillus membrane. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 16, 2023The c.1552A>G (p.M518V) alteration is located in exon 11 (coding exon 11) of the SLC7A8 gene. This alteration results from a A to G substitution at nucleotide position 1552, causing the methionine (M) at amino acid position 518 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
