Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 02, 2023The c.427G>A (p.V143M) alteration is located in exon 4 (coding exon 4) of the TMEM39B gene. This alteration results from a G to A substitution at nucleotide position 427, causing the valine (V) at amino acid position 143 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
