Submissions by phenotype
not specified Uncertain:1
The c.1325G>A (p.S442N) alteration is located in exon 4 (coding exon 4) of the TMCC3 gene. This alteration results from a G to A substitution at nucleotide position 1325, causing the serine (S) at amino acid position 442 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
