Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.47C>A (p.S16Y) alteration is located in exon 1 (coding exon 1) of the SPCS1 gene. This alteration results from a C to A substitution at nucleotide position 47, causing the serine (S) at amino acid position 16 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
