The c.194C>T (p.S65L) alteration is located in exon 2 (coding exon 2) of the ZCCHC4 gene. This alteration results from a C to T substitution at nucleotide position 194, causing the serine (S) at amino acid position 65 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
