Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 15, 2024The c.571C>T (p.R191W) alteration is located in exon 8 (coding exon 7) of the SNRNP70 gene. This alteration results from a C to T substitution at nucleotide position 571, causing the arginine (R) at amino acid position 191 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
