The c.610T>C (p.F204L) alteration is located in exon 6 (coding exon 6) of the YIPF4 gene. This alteration results from a T to C substitution at nucleotide position 610, causing the phenylalanine (F) at amino acid position 204 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
