Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 16, 2024The c.1642C>T (p.R548W) alteration is located in exon 10 (coding exon 9) of the SH2D3A gene. This alteration results from a C to T substitution at nucleotide position 1642, causing the arginine (R) at amino acid position 548 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
