Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 15, 2023The c.458A>C (p.N153T) alteration is located in exon 8 (coding exon 7) of the TMEM40 gene. This alteration results from a A to C substitution at nucleotide position 458, causing the asparagine (N) at amino acid position 153 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
