Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 04, 2022The c.194G>T (p.R65L) alteration is located in exon 3 (coding exon 3) of the SPEF2 gene. This alteration results from a G to T substitution at nucleotide position 194, causing the arginine (R) at amino acid position 65 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
