Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 28, 2023The c.355G>A (p.V119M) alteration is located in exon 3 (coding exon 3) of the TMEM38A gene. This alteration results from a G to A substitution at nucleotide position 355, causing the valine (V) at amino acid position 119 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
