The c.269T>G (p.F90C) alteration is located in exon 1 (coding exon 1) of the RNPEPL1 gene. This alteration results from a T to G substitution at nucleotide position 269, causing the phenylalanine (F) at amino acid position 90 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
