Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 28, 2024The c.79G>A (p.G27R) alteration is located in exon 1 (coding exon 1) of the TMPRSS12 gene. This alteration results from a G to A substitution at nucleotide position 79, causing the glycine (G) at amino acid position 27 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
