Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 01, 2021The c.128A>T (p.Q43L) alteration is located in exon 1 (coding exon 1) of the TMPRSS12 gene. This alteration results from a A to T substitution at nucleotide position 128, causing the glutamine (Q) at amino acid position 43 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
