The c.1102C>A (p.P368T) alteration is located in exon 8 (coding exon 8) of the CECR5 gene. This alteration results from a C to A substitution at nucleotide position 1102, causing the proline (P) at amino acid position 368 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
