The c.947C>T (p.T316M) alteration is located in exon 6 (coding exon 5) of the SCML4 gene. This alteration results from a C to T substitution at nucleotide position 947, causing the threonine (T) at amino acid position 316 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
