Description

The c.1360G>T (p.A454S) alteration is located in exon 1 (coding exon 1) of the PCDHA8 gene. This alteration results from a G to T substitution at nucleotide position 1360, causing the alanine (A) at amino acid position 454 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
