Collection Method: clinical testing

The c.327C>A (p.F109L) alteration is located in exon 1 (coding exon 1) of the LRRC10B gene. This alteration results from a C to A substitution at nucleotide position 327, causing the phenylalanine (F) at amino acid position 109 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
