not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 27, 2023The c.1787C>A (p.T596N) alteration is located in exon 13 (coding exon 12) of the RBBP8NL gene. This alteration results from a C to A substitution at nucleotide position 1787, causing the threonine (T) at amino acid position 596 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
