The c.835C>T (p.L279F) alteration is located in exon 7 (coding exon 6) of the ZNF641 gene. This alteration results from a C to T substitution at nucleotide position 835, causing the leucine (L) at amino acid position 279 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
