Collection Method:clinical testing

The c.1669C>T (p.P557S) alteration is located in exon 12 (coding exon 11) of the SRBD1 gene. This alteration results from a C to T substitution at nucleotide position 1669, causing the proline (P) at amino acid position 557 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
