Genes affected
ZNF644 (HGNC:29222): (zinc finger protein 644) The protein encoded by this gene is a zinc finger transcription factor that may play a role in eye development. Defects in this gene have been associated with high myopia. Three transcript variants encoding two different isoforms have been found for this gene. [provided by RefSeq, Aug 2011]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 02, 2024The c.3354A>G (p.I1118M) alteration is located in exon 4 (coding exon 3) of the ZNF644 gene. This alteration results from a A to G substitution at nucleotide position 3354, causing the isoleucine (I) at amino acid position 1118 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
