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 GeneticsJun 10, 2024The c.623A>G (p.Q208R) alteration is located in exon 4 (coding exon 4) of the SLC7A8 gene. This alteration results from a A to G substitution at nucleotide position 623, causing the glutamine (Q) at amino acid position 208 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
