Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 23, 2024The c.143C>T (p.T48I) alteration is located in exon 2 (coding exon 1) of the TPRG1 gene. This alteration results from a C to T substitution at nucleotide position 143, causing the threonine (T) at amino acid position 48 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
