Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 27, 2023The c.8030G>A (p.R2677Q) alteration is located in exon 21 (coding exon 21) of the TRANK1 gene. This alteration results from a G to A substitution at nucleotide position 8030, causing the arginine (R) at amino acid position 2677 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
