Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 03, 2023The c.237A>T (p.K79N) alteration is located in exon 3 (coding exon 3) of the TMEM260 gene. This alteration results from a A to T substitution at nucleotide position 237, causing the lysine (K) at amino acid position 79 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
