The c.4433T>C (p.L1478S) alteration is located in exon 14 (coding exon 14) of the ERICH3 gene. This alteration results from a T to C substitution at nucleotide position 4433, causing the leucine (L) at amino acid position 1478 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
