Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 06, 2023The c.1333C>A (p.Q445K) alteration is located in exon 8 (coding exon 7) of the EXOC3L1 gene. This alteration results from a C to A substitution at nucleotide position 1333, causing the glutamine (Q) at amino acid position 445 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
