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]

The c.703G>C (p.A235P) alteration is located in exon 5 (coding exon 5) of the SLC7A8 gene. This alteration results from a G to C substitution at nucleotide position 703, causing the alanine (A) at amino acid position 235 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
