Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 10, 2022The c.1304G>A (p.R435H) alteration is located in exon 8 (coding exon 7) of the EXOC3L1 gene. This alteration results from a G to A substitution at nucleotide position 1304, causing the arginine (R) at amino acid position 435 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
