Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 26, 2022The c.236C>A (p.A79E) alteration is located in exon 2 (coding exon 2) of the SP9 gene. This alteration results from a C to A substitution at nucleotide position 236, causing the alanine (A) at amino acid position 79 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
