Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 17, 2024The c.947C>T (p.A316V) alteration is located in exon 2 (coding exon 2) of the SP9 gene. This alteration results from a C to T substitution at nucleotide position 947, causing the alanine (A) at amino acid position 316 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
