Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 05, 2023The c.4938G>T (p.K1646N) alteration is located in exon 37 (coding exon 37) of the TMEM131 gene. This alteration results from a G to T substitution at nucleotide position 4938, causing the lysine (K) at amino acid position 1646 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
