Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 27, 2024The c.1370T>A (p.L457Q) alteration is located in exon 8 (coding exon 7) of the SH2D3A gene. This alteration results from a T to A substitution at nucleotide position 1370, causing the leucine (L) at amino acid position 457 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
