The c.941C>T (p.S314L) alteration is located in exon 6 (coding exon 6) of the UNC93A gene. This alteration results from a C to T substitution at nucleotide position 941, causing the serine (S) at amino acid position 314 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
