Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 31, 2023The c.354T>G (p.S118R) alteration is located in exon 2 (coding exon 2) of the SPESP1 gene. This alteration results from a T to G substitution at nucleotide position 354, causing the serine (S) at amino acid position 118 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
