Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 26, 2022The c.62G>A (p.G21D) alteration is located in exon 1 (coding exon 1) of the TMEM30A gene. This alteration results from a G to A substitution at nucleotide position 62, causing the glycine (G) at amino acid position 21 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
