The c.271C>T (p.L91F) alteration is located in exon 3 (coding exon 3) of the CWH43 gene. This alteration results from a C to T substitution at nucleotide position 271, causing the leucine (L) at amino acid position 91 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
