Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.179G>A (p.R60H) alteration is located in exon 3 (coding exon 3) of the PLEKHA8 gene. This alteration results from a G to A substitution at nucleotide position 179, causing the arginine (R) at amino acid position 60 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
