Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 04, 2022The c.482G>T (p.R161L) alteration is located in exon 7 (coding exon 4) of the SSUH2 gene. This alteration results from a G to T substitution at nucleotide position 482, causing the arginine (R) at amino acid position 161 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
