Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 07, 2023The c.689G>A (p.R230Q) alteration is located in exon 5 (coding exon 4) of the TBCEL gene. This alteration results from a G to A substitution at nucleotide position 689, causing the arginine (R) at amino acid position 230 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
