Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 15, 2023The c.919G>T (p.D307Y) alteration is located in exon 5 (coding exon 5) of the SLC7A6OS gene. This alteration results from a G to T substitution at nucleotide position 919, causing the aspartic acid (D) at amino acid position 307 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
