Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 20, 2024The c.1559A>C (p.Q520P) alteration is located in exon 9 (coding exon 8) of the SH2D3A gene. This alteration results from a A to C substitution at nucleotide position 1559, causing the glutamine (Q) at amino acid position 520 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
