Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 02, 2024The c.268C>T (p.R90W) alteration is located in exon 3 (coding exon 3) of the SSC5D gene. This alteration results from a C to T substitution at nucleotide position 268, causing the arginine (R) at amino acid position 90 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
