Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 07, 2022The c.874C>T (p.R292W) alteration is located in exon 7 (coding exon 7) of the STPG2 gene. This alteration results from a C to T substitution at nucleotide position 874, causing the arginine (R) at amino acid position 292 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
