Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.304C>T (p.H102Y) alteration is located in exon 5 (coding exon 5) of the CATSPERD gene. This alteration results from a C to T substitution at nucleotide position 304, causing the histidine (H) at amino acid position 102 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
