Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 30, 2021The c.348G>A (p.M116I) alteration is located in exon 2 (coding exon 2) of the TSPOAP1 gene. This alteration results from a G to A substitution at nucleotide position 348, causing the methionine (M) at amino acid position 116 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
