Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 01, 2024The c.728T>C (p.I243T) alteration is located in exon 7 (coding exon 7) of the GLRA3 gene. This alteration results from a T to C substitution at nucleotide position 728, causing the isoleucine (I) at amino acid position 243 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
