Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 23, 2022The c.1129A>G (p.I377V) alteration is located in exon 8 (coding exon 7) of the TMEM39A gene. This alteration results from a A to G substitution at nucleotide position 1129, causing the isoleucine (I) at amino acid position 377 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
