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 26, 2023The c.1075G>A (p.V359M) alteration is located in exon 8 (coding exon 8) of the SLC7A8 gene. This alteration results from a G to A substitution at nucleotide position 1075, causing the valine (V) at amino acid position 359 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
