Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 26, 2021The c.898A>G (p.R300G) alteration is located in exon 8 (coding exon 8) of the TGM4 gene. This alteration results from a A to G substitution at nucleotide position 898, causing the arginine (R) at amino acid position 300 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
