Collection Method: clinical testing

The c.435T>A (p.F145L) alteration is located in exon 5 (coding exon 4) of the GPATCH11 gene. This alteration results from a T to A substitution at nucleotide position 435, causing the phenylalanine (F) at amino acid position 145 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
