The c.253C>T (p.P85S) alteration is located in exon 2 (coding exon 1) of the TMEM200A gene. This alteration results from a C to T substitution at nucleotide position 253, causing the proline (P) at amino acid position 85 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
