Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 25, 2024The c.866G>A (p.G289D) alteration is located in exon 6 (coding exon 6) of the TMEM38A gene. This alteration results from a G to A substitution at nucleotide position 866, causing the glycine (G) at amino acid position 289 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
