The c.1427T>G (p.F476C) alteration is located in exon 11 (coding exon 11) of the EFCAB14 gene. This alteration results from a T to G substitution at nucleotide position 1427, causing the phenylalanine (F) at amino acid position 476 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
