Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 19, 2023The c.452A>G (p.N151S) alteration is located in exon 4 (coding exon 4) of the SPEF2 gene. This alteration results from a A to G substitution at nucleotide position 452, causing the asparagine (N) at amino acid position 151 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
