The c.1205C>T (p.T402I) alteration is located in exon 10 (coding exon 9) of the RBBP8NL gene. This alteration results from a C to T substitution at nucleotide position 1205, causing the threonine (T) at amino acid position 402 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
