Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 05, 2022The c.521A>G (p.N174S) alteration is located in exon 3 (coding exon 3) of the SIRPD gene. This alteration results from a A to G substitution at nucleotide position 521, causing the asparagine (N) at amino acid position 174 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
