Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.1411C>T (p.R471C) alteration is located in exon 9 (coding exon 8) of the SCARA5 gene. This alteration results from a C to T substitution at nucleotide position 1411, causing the arginine (R) at amino acid position 471 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
