Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 27, 2024The c.506T>G (p.V169G) alteration is located in exon 2 (coding exon 2) of the SPATA25 gene. This alteration results from a T to G substitution at nucleotide position 506, causing the valine (V) at amino acid position 169 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
