Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 26, 2023The c.446G>A (p.R149Q) alteration is located in exon 4 (coding exon 4) of the TARM1 gene. This alteration results from a G to A substitution at nucleotide position 446, causing the arginine (R) at amino acid position 149 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
