Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 06, 2021The c.949C>T (p.R317W) alteration is located in exon 7 (coding exon 7) of the PTAR1 gene. This alteration results from a C to T substitution at nucleotide position 949, causing the arginine (R) at amino acid position 317 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
