Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 07, 2024The c.304A>G (p.I102V) alteration is located in exon 3 (coding exon 3) of the SPEF2 gene. This alteration results from a A to G substitution at nucleotide position 304, causing the isoleucine (I) at amino acid position 102 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
