The c.848A>T (p.Y283F) alteration is located in exon 8 (coding exon 8) of the NCBP3 gene. This alteration results from a A to T substitution at nucleotide position 848, causing the tyrosine (Y) at amino acid position 283 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
