Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 12, 2024The c.1591C>A (p.R531S) alteration is located in exon 10 (coding exon 9) of the EXOC3L1 gene. This alteration results from a C to A substitution at nucleotide position 1591, causing the arginine (R) at amino acid position 531 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
