Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 27, 2022The c.1498T>C (p.S500P) alteration is located in exon 10 (coding exon 9) of the EXOC3L1 gene. This alteration results from a T to C substitution at nucleotide position 1498, causing the serine (S) at amino acid position 500 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
