The c.688C>T (p.H230Y) alteration is located in exon 4 (coding exon 2) of the PTER gene. This alteration results from a C to T substitution at nucleotide position 688, causing the histidine (H) at amino acid position 230 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
